Check Digit Verification of cas no

The CAS Registry Mumber 138212-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,1 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138212-47:
(8*1)+(7*3)+(6*8)+(5*2)+(4*1)+(3*2)+(2*4)+(1*7)=112
112 % 10 = 2
So 138212-47-2 is a valid CAS Registry Number.

Stereodivergent Approach to β-Hydroxy α-Amino Acids from C2-Symmetrical Alk-2-yne-1,4-diols

Amador, Marta,Ariza, Xavier,Garcia, Jordi,Sevilla, Sara

, p. 4511 - 4514 (2007/10/03)

(Matrix Presented) A new stereodivergent route to erythro- and threo-β-substituted serines from a common C2-symmetrical alk-2-yne-1,4-diol is described. Stereocontrol in such an acyclic system is achieved by taking advantage of symmetry. Stereo

Silver(I) Catalyzed Amino Cyclization of O-(2,3-Butadienyl) Carbamates: An Efficient and Stereoselective Synthesis of 4-Vinyl-2-oxazolidinones

Kimura, Masanari,Fugami, Keigo,Tanaka, Shuji,Tamaru, Yoshinao

, p. 6359 - 6362 (2007/10/02)

Silver(I) salts catalyze an amino cyclization of O-(2,3-butadienyl) N-tosyl-carbamates to provide mixtures of cis and trans-5-substituted N-tosyl-4-vinyl-2-oxazolidinones, the trans-isomers predominantly or exclusively.
