Check Digit Verification of cas no

The CAS Registry Mumber 857682-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,6,8 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 857682-09:
(8*8)+(7*5)+(6*7)+(5*6)+(4*8)+(3*2)+(2*0)+(1*9)=218
218 % 10 = 8
So 857682-09-8 is a valid CAS Registry Number.

Practical synthesis of chiral cis-cyclohex-4-ene-1,2-dicarboxylic acid derivatives by utilizing (4S)-isopropyl-1,3-thiazolidine-2-thione

Van Dang, Tinh,Miyamoto, Motoyuki,Sano, Shigeki,Shiro, Motoo,Nagao, Yoshimitsu

, p. 1139 - 1157 (2007/10/03)

Both enantiomers of chiral cis-cyclohex-4-ene-1,2-dicarboxylic acid derivatives were synthesized by optical resolution of the corresponding enantiomeric mixtures by utilizing (4S)-isopropyl-1,3-thiazolidine-2-thione followed by mild aminolysis, methanolys
