Check Digit Verification of cas no
The CAS Registry Mumber 7745-18-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,4 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7745-18:
(6*7)+(5*7)+(4*4)+(3*5)+(2*1)+(1*8)=118
118 % 10 = 8
So 7745-18-8 is a valid CAS Registry Number.

SYNTHESIS OF 19-HYDROXYSTEROIDS I. NEW SYNTHESIS OF 19-HYDROXYTESTOSTERONE
Kovganko, N. V.,Kashkan, Zh. N.,Chernov, Yu. G.
, p. 584 - 588 (2007/10/02)
For obtaining 19-hydroxytestosterone from dehydroepiandrosterone a new scheme of synthesis has been developed the key stages of which are the reduction of the 17-keto group to a 17-alcohol, the functionalization of the 19-methyl group via the bromohydrin with the formation of a 6β,19-epoxide, the selective hydrolysis of the free β-acetoxy group, the conversion of the 3β-hydroxy-5α-bromo derivative into the Δ4-3-ketone, and the reductive cleavage of the 6β,19-epoxide ring.
