Check Digit Verification of cas no

The CAS Registry Mumber 185851-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,8,5 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 185851-22:
(8*1)+(7*8)+(6*5)+(5*8)+(4*5)+(3*1)+(2*2)+(1*2)=163
163 % 10 = 3
So 185851-22-3 is a valid CAS Registry Number.

Concise synthesis of taxol A-ring components: Remote diastereoselective additions of alkenyl lithiums to aldehydes

Frost, Christopher,Linnane, Patrick,Magnus, Philip,Spyvee, Mark

, p. 9139 - 9142 (1996)

The acid chloride 6 provides access to 7 (R,S and S,S) which upon bromine-lithium exchange undergoes remarkably highly diastereoselective additions to aldehydes; 7 is also readily elaborated into the acetal 10.
