Check Digit Verification of cas no

The CAS Registry Mumber 138702-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,0 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138702-89:
(8*1)+(7*3)+(6*8)+(5*7)+(4*0)+(3*2)+(2*8)+(1*9)=143
143 % 10 = 3
So 138702-89-3 is a valid CAS Registry Number.

Bifunctional chiral auxiliaries 7: Aldol reactions of enolates derived from 1,3-diacylimidazolidine-2-thiones and 1,3-diacylimidazolidin-2-ones

Davies,Edwards,Evans,Mortlock

, p. 6621 - 6642 (1994)

Dibutylboron enolates of 1,3-diacylimidazolidine-2-thiones and 1,3-diacylimidazolidin-2-ones undergo highly syn-stereoselective aldol reactions with aldehydes to allow elaboration of both acyl sidechains. The reaction is proposed to occur via sequential e
