Check Digit Verification of cas no

The CAS Registry Mumber 174716-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,7,1 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 174716-72:
(8*1)+(7*7)+(6*4)+(5*7)+(4*1)+(3*6)+(2*7)+(1*2)=154
154 % 10 = 4
So 174716-72-4 is a valid CAS Registry Number.

Synthesis of steroidal [4,6-b,c]-benzothiazepines, a new class of aromatase inhibitor

Holland,Kumaresan,Lakshmaiah

, p. 2185 - 2189 (1995)

Several steroidal [4,6-b,c]benzothiazepines have been prepared via base-catalyzed Michael addition of 2-aminothiophenol to 3β,17β-diacetoxyandrost-4-en-6-one. The product of this reaction has the 4β,5α stereochemisty, but cyclizes to a benzothiazepine with the steroidal 4β,5β configuration, confirmed by X-ray crystallographic analysis. 2-Aminothiophenol reacts with 3β,17β-diacetoxyandrost-4-en-6-one under acidic conditions to give a steroidal 6-spiro-benzothiazole. An androst-4-ene-3,17-dione-based [4,6]benzothiazepine has been shown to be a moderate competitive inhibitor of the human placental aromatase enzyme with IC50 = 42.3 μM.
