Check Digit Verification of cas no

The CAS Registry Mumber 104461-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,6 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104461-88:
(8*1)+(7*0)+(6*4)+(5*4)+(4*6)+(3*1)+(2*8)+(1*8)=103
103 % 10 = 3
So 104461-88-3 is a valid CAS Registry Number.

, p. 5433 - 5436 (1985)

The synthesis of the optically active 4 has been accomplished by asymmetric formation of cyclic β-keto esters fully substituted at the α Carbon followed by chemoselective reduction of the ester group.Of the asymmetric reactions examined the Koga procedure proved to be the most selective.
