Check Digit Verification of cas no

The CAS Registry Mumber 17958-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,5 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17958-41:
(7*1)+(6*7)+(5*9)+(4*5)+(3*8)+(2*4)+(1*1)=147
147 % 10 = 7
So 17958-41-7 is a valid CAS Registry Number.

NEW CHIRAL RECOGNITION OF CHIRAL TIN(II) ENOLATES TOWARD CYCLIC ACYL IMINIUM SPECIES. ASYMMETRIC TOTAL SYNTHESIS OF (-)-SUPINIDINE

Nagao, Yoshimitsu,Dai, Wei-Min,Ochiai, Masahito

, p. 6133 - 6136 (2007/10/02)

Diastereoselective alkylation of chiral tin(II) enolates 1 onto cyclic acyl iminium ion 7 proceeded in a different chiral recognition mode from the case of 1 onto cyclic acyl imines 3.This new diastereoselective alkylation was efficiently utilized for an asymmetric total synthesis of (-)-supinidine (20).
