Check Digit Verification of cas no

The CAS Registry Mumber 144686-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,8 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144686-83:
(8*1)+(7*4)+(6*4)+(5*6)+(4*8)+(3*6)+(2*8)+(1*3)=159
159 % 10 = 9
So 144686-83-9 is a valid CAS Registry Number.

Baker's yeast-induced asymmetric reduction of the keto group activated by the cyclopropane unit

Tkachev,Rukavishnikov,Gatilov,Bagrjanskaja

, p. 1165 - 1187 (1992)

Certain cis-3-substituted 2,2-dimethyl-1-(2-oxopropyl)-cyclopropanes are effectively reduced by baker's yeast to give predominantly (S)-isomers of the corresponding 2-hydroxypropyl derivatives. Reduction of the 2-oxopropyl group proceeds more rapidly (ca.
