Check Digit Verification of cas no
The CAS Registry Mumber 868-59-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 868-59:
(5*8)+(4*6)+(3*8)+(2*5)+(1*9)=107
107 % 10 = 7
So 868-59-7 is a valid CAS Registry Number.

Novel thiazolidine derivatives as chiral catalysts in the enantioselective addition of diethylzinc to aldehydes
Meng, Qinglin,Li, Yuelan,He, Yan,Guan, Yedi
, p. 4255 - 4261 (2007/10/03)
New chiral thiazolidine derivatives were synthesized conveniently from natural L-cysteine and showed good enantioselectivity (up to 90% ee) in the addition of diethylzinc to aldehydes. The catalytic efficiency of the thiazolidine derivatives is influenced by the different structures of the thiazolidine rings and the bulkiness of R moiety in the ester groups.
