Check Digit Verification of cas no

The CAS Registry Mumber 256221-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,2,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 256221-71:
(8*2)+(7*5)+(6*6)+(5*2)+(4*2)+(3*1)+(2*7)+(1*1)=123
123 % 10 = 3
So 256221-71-3 is a valid CAS Registry Number.

Reaction of 3β-chloro-5α,6α-epoxysteroids with trifluoroacetic acid

Kovganko,Ananich

, p. 179 - 181 (1999)

It has been established that on the interaction of the 5α,6α-epoxysteroids (1a-c) with trifluoroacetic acid in chloroform the 6-trifluoroacetates of the 5α,6β-diols (2a-c) are formed in high yield. The alkaline hydrolysis of the trifluoroacetates (2a-c) leads to the corresponding diols (3a-c).

Interaction of 3-β-chloro-Δ5-steroids with trifluoroperacetic acid

Kovganko,Drozdov,Ananich

, p. 75 - 79 (2007/10/03)

It has been established that the reaction of 3β-chloro-Δ5-steroids with trifluoroperacetic acid forms not only the 5a,6-peroxides (3a,d), but also the 5a,6β-diols (5a,b,d) and their 6-trifluoroacetates.
