Check Digit Verification of cas no

The CAS Registry Mumber 444308-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,3,0 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 444308-38:
(8*4)+(7*4)+(6*4)+(5*3)+(4*0)+(3*8)+(2*3)+(1*8)=137
137 % 10 = 7
So 444308-38-7 is a valid CAS Registry Number.

Synthesis of a new (1R)-(-)-myrtenal-derived dioxadithiadodecacycle and its use as an efficient chiral auxiliary

Vargas-Diaz, M. Elena,Joseph-Nathan, Pedro,Tamariz, Joaquin,Zepeda, L. Gerardo

, p. 13 - 16 (2007/10/03)

(Chemical Equation Presented) The new macrocycle 9 (>70% yield from hydroxythiol 10) was treated with several nucleophilic reagents (RMgX, RLi, and LiAlH4) affording carbinols 12a-j (80-96% yield, >99:1 dr). Oxidative hydrolysis of 12a,c,e, followed by LiAlH4 reduction of the resulting mixture, gave 16a,c,e in >95% ee,16c being a key precursor for the preparation of fungicide 17. The absolute configuration of 9 and 12j (Nu = H) was established by single-crystal X-ray diffraction analyses and chemical correlation.

Enantioselective synthesis of 1-alkyl-substituted 1-phenyl-1,2-ethanediols using a myrtenal-derived chiral auxiliary

Vargas-Diaz, Maria Elena,Chacon-Garcia, Luis,Velazquez, Pedro,Tamariz, Joaquin,Joseph-Nathan, Pedro,Zepeda, L. Gerardo

, p. 3225 - 3232 (2007/10/03)

The enantioselective synthesis of several 1-phenyl-1,2-ethanodiol derivatives using 2-benzoyl-1,3-oxathiane 1 as a chiral auxiliary is described. Nucleophilic additions of Grignard reagents, methyl lithium and LS-Selectride on benzoyloxathiane 1 proceeded in >95% diastereomeric ratio (dr) affording the corresponding tertiary carbinols, which were successively hydrolyzed and reduced to give the title derivatives in >95% enantiomeric excess (ee).

Highly diastereoselective nucleophilic additions using a novel myrtenal-derived oxathiane as a chiral auxiliary

Martinez-Ramos, Federico,Vargas-Diaz, Maria Elena,Chacon-Garcia, Luis,Tamariz, Joaquin,Joseph-Nathan, Pedro,Zepeda

, p. 3095 - 3103 (2007/10/03)

The synthesis of novel oxathiane 3 and its acetyl derivative 12, from commercially available (-)-myrtenal 4, is described. The addition of several nucleophilic reagents to 12 furnished the corresponding tertiary carbinols in highly diastereomeric excess. The hydrolysis of 11a, b yielded the expected α-hydroxycarbonyl compounds in excellent enantiomeric excess.
