Check Digit Verification of cas no

The CAS Registry Mumber 61981-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 61981-56:
(7*6)+(6*1)+(5*9)+(4*8)+(3*1)+(2*5)+(1*6)=144
144 % 10 = 4
So 61981-56-4 is a valid CAS Registry Number.

Stereospecific Synthesis of α-Deuteriated α-Amino Acids: Regiospecific Deuteriation of Chiral 3-Isopropyl-2,5-dimethoxy-3,6-dihydropyrazines

Rose, Janet E.,Leeson, Paul D.,Gani, David

, p. 157 - 166 (1995)

Base-catalysed deuteriation of (3R)- or (3S)-3-isopropyl-2,5-dimethoxy-3,6-dihydropyrazines in refluxing CH3O2H-2H2O gives the -isotopomer in excellent yields without disturbing the stereogenic centre at C-3.These compounds provide convenient and efficient access to a range of (R)- and (S)-α-deuteriated α-amino acids, including serine, aspartic acid, allylglycine and phenylalanine, via alkylation of the butyllithium generated C-6 anion.
