Check Digit Verification of cas no

The CAS Registry Mumber 28192-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,9 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28192-95:
(7*2)+(6*8)+(5*1)+(4*9)+(3*2)+(2*9)+(1*5)=132
132 % 10 = 2
So 28192-95-2 is a valid CAS Registry Number.

Introducing Δ11 unsaturation into steroid compounds

-

, (2008/06/13)

A process for the introduction of Δ11 unsaturation into steroid compounds having a C-12 sulfonate ester group is described. Dehydrosulfonation is carried out by reacting the sulfonate with a hexaalkylphosphoric triamide. The process is particularly useful with steroid compounds that also contain a blocked C-7 hydroxy group. The process yields the 11-enate in preference to the 6,11-dienate. The yield of the process can be increased by carrying out the reaction in the presence of a weak base.
