Check Digit Verification of cas no

The CAS Registry Mumber 259822-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,8,2 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 259822-62:
(8*2)+(7*5)+(6*9)+(5*8)+(4*2)+(3*2)+(2*6)+(1*2)=173
173 % 10 = 3
So 259822-62-3 is a valid CAS Registry Number.

The first asymmetric syntheses of L-homocysteine and L-homocystine

Adamczyk, Maciej,Fishpaugh, Jeffrey R.,Thiruvazhi, Mohan

, p. 4151 - 4156 (1999)

Asymmetric syntheses of L-homocysteine 1 and L-homocystine 2 are described. Alkylation of the carbanion derived from Schollkopf reagent 3 and ensuing hydrolyses gave S-triphenylmethyl-L-homocysteine 6. Removal of the triphenylmethyl group gave L-homocysteine 1 and subsequent oxidation provided L-homocystine 2.
