Check Digit Verification of cas no

The CAS Registry Mumber 116611-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,1 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116611-50:
(8*1)+(7*1)+(6*6)+(5*6)+(4*1)+(3*1)+(2*5)+(1*0)=98
98 % 10 = 8
So 116611-50-8 is a valid CAS Registry Number.

A NOVEL APPROACH TO THE SYNTHESIS OF OPTICALLY PURE NON PROTEIN α-AMINO ACIDS IN BOTH L AND D CONFIGURATIONS FROM L-SERINE

Sasaki, N.Andre,Hashimoto, Chiyomi,Potier, Pierre

, p. 6069 - 6072 (2007/10/02)

Efficient syntheses of (2R)-2-Boc-amino-3-phenylsulfonyl-1-propanol 3 and its enantiomer 9 from L-serine are described.The potential of these compounds in a novel general method for the synthesis of optically pure non protein α-amino acids in both the L and D configurations is exemplified by the preparation of N-Boc-L-and D-homophenylalanine,-norvaline and -norleucine.
