Check Digit Verification of cas no
The CAS Registry Mumber 312746-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,7,4 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 312746-71:
(8*3)+(7*1)+(6*2)+(5*7)+(4*4)+(3*6)+(2*7)+(1*1)=127
127 % 10 = 7
So 312746-71-7 is a valid CAS Registry Number.

An efficient procedure was developed for the asymmetric synthesis of S-alkyl derivatives of (R)-cysteine by nucleophilic addition of alkanethiols (BunSH, ButSH, or tert-C5H11SH) to the C=C bond of the dehydroalanine fragment in the Ni11 complex of the Schiff's base of Δ-Ala with (S)-2-N-(N-benzylprolyl)aminobenzophenone [(S)-BPB-Δ-Ala]Ni11. Under conditions of thermodynamic control of the reaction, the diastereomeric excess of the complexes with the (S,R)-configuration was 88 - 96%. After decomposition of the complexes, (R)-S-butylcysteine, (R)-S-tert-butylcysteine, and (R)-S-tert-pentylcysteine were isolated with an enantiomeric purity of >97%.
