Check Digit Verification of cas no
The CAS Registry Mumber 14752-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,5 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14752-61:
(7*1)+(6*4)+(5*7)+(4*5)+(3*2)+(2*6)+(1*1)=105
105 % 10 = 5
So 14752-61-5 is a valid CAS Registry Number.

Diastereoselective Addition of Prochiral Nucleophilic Alkenes to α-Chiral N-Sulfonyl Imines
Ando, Kaori,Fettinger, James,Gutierrez, David A.,Houk, K. N.,Shaw, Jared T.
supporting information, p. 1164 - 1168 (2022/02/14)
The Lewis-acid-promoted addition of prochiral E- and Z-allyl nucleophiles to chiral α-alkoxy N-tosyl imines is described. Alkene geometry is selectively transferred to the newly formed carbon-carbon bond, resulting in stereochemical control of C1, C2, and C3 of the resulting 2-alkoxy-3-N-tosyl-4-alkyl-5-hexene products. A computational analysis to elucidate the high selectivity is also presented. This methodology was employed in the synthesis of two naturally occurring isomers of clausenamide.
Improved syntheses of methyl (14E)- and (14Z)-dehydrocrepenynate: Key intermediates in plant and fungal polyacetylene biosynthesis
Zhu, Lizhi,Minto, Robert E.
, p. 3803 - 3805 (2007/10/03)
Efficient syntheses of the (14E)- and (14Z)-isomers of methyl dehydrocrepenynate have been achieved. The key steps involve Pd-catalyzed cross-coupling reactions furnishing the C=C double bonds between C14 and C15, followed by Wittig reactions to construct the (Z)-alkene at C9. High overall yields and stereoselectivities were achieved for both isomers.
Terminal 1-halo and 1-pseudohalo-1-alkynes via Bis(trimethylsilyl)peroxide (BTMSPO) promoted Umpolung transfer of halides and pseudohalides
Casarini,Dembech,Reginato,Ricci,Seconi
, p. 2169 - 2170 (2007/10/02)
Reaction of terminal acetylenes with readily available and inexpensive copper and zinc halides and pseudo-halides and BTMSPO has been found to be an effective and general route for obtaining, in the absence of bases and under mild conditions, 1-halo and 1-pseudohalo-1-alkynes in generally good yields.
