Check Digit Verification of cas no

The CAS Registry Mumber 104476-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,7 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104476-85:
(8*1)+(7*0)+(6*4)+(5*4)+(4*7)+(3*6)+(2*8)+(1*5)=119
119 % 10 = 9
So 104476-85-9 is a valid CAS Registry Number.

BOTRYDIAL SYNTHETIC STUDIES. ASYMMETRIC SYNTHESIS OF QUATERNARY CARBON CENTRES.

Kunisch, Franz,Hobert, Kurt,Welzel, Peter

, p. 5433 - 5436 (2007/10/02)

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.
