Check Digit Verification of cas no

The CAS Registry Mumber 3227-12-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,2 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3227-12:
(6*3)+(5*2)+(4*2)+(3*7)+(2*1)+(1*2)=61
61 % 10 = 1
So 3227-12-1 is a valid CAS Registry Number.

Steroids 54. Amino acylamidosteroids

Vincze, Iren,Hackler, Laszlo,Szendi, Zsuzsa,Schneider, Gyula

, p. 697 - 702 (2007/10/03)

Aminosteroids were prepared and acylated with protected amino acids by means of the mixed anhydride or the active ester method. The tert- butyloxycarbonyl-(BOC) protecting group was eliminated by acidolysis, and the benzyloxycarbonyl-(Z) group by catalytic hydrogenation. 3β- and 6β- Glycylamidosteroids were prepared by indirect amination of chloroacetamido derivatives, formed by the Ritter reaction on the corresponding 3α,5α- cyclo and 5α,6α-epoxy steroids. Water soluble double salts were produced from the compounds for pharmacological investigations.
