Check Digit Verification of cas no

The CAS Registry Mumber 79409-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79409-33:
(7*7)+(6*9)+(5*4)+(4*0)+(3*9)+(2*3)+(1*3)=159
159 % 10 = 9
So 79409-33-9 is a valid CAS Registry Number.

Alkylated Steroids. Part 3. The 21-Alkylation of 20-Oxopregnanes and Synthesis of a Novel Anti-inflammatory 16α,17α,21-Trimethyl Steroid (Org 6216)

Cairns, James,Logan, Robert T.,McGarry, George,Roy, Robert G.,Stevenson, Donald F. M.,Woods, Gilbert F.

, p. 2306 - 2316 (1981)

The development of a 21-alkylation reaction which proceeds via the lithium 20(21)-enolate is described and ats scope demonstrated by the preparation of a variety of 21-alkylpregnane derivatives.Application of this process to 11β-acetoxy-16α,17α-dimethyl-5α-pregnane-3,20-dione (28a) and its 5β-analogue (28b) led to the corresponding 16α,17α,21-trimethyl derivatives.Several routes from these saturated trimethylpregnane-3,20-diones to 11β-hydroxy-16α,17α,21-trimethylpregna-1,4-diene-3,20-dione (Org 6216) were explored.The best method gave Org 6216 in 75percent yield.
