Check Digit Verification of cas no

The CAS Registry Mumber 4993-32-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4993-32:
(6*4)+(5*9)+(4*9)+(3*3)+(2*3)+(1*2)=122
122 % 10 = 2
So 4993-32-2 is a valid CAS Registry Number.

Reduction of steroidal ketones with amine - Boranes

Leontjev,Vasiljeva,Pivnitsky

, p. 703 - 708 (2007/10/03)

Complexes of secondary amines with borane, R2NH·BH 3, surpass sodium borohydride as reducing agents for saturated and unsaturated steroidal 3-, 12-, 17-, and 20-ketones as regards chemo- and regioselectivity and mildness of the reaction conditions. In the case of 12-ketones, stereoselectivity is also improved.
