Check Digit Verification of cas no

The CAS Registry Mumber 191029-88-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,0,2 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 191029-88:
(8*1)+(7*9)+(6*1)+(5*0)+(4*2)+(3*9)+(2*8)+(1*8)=136
136 % 10 = 6
So 191029-88-6 is a valid CAS Registry Number.

Highly diastereoselective synthesis of 11β,17β-diaryl-18a-homo-19-nor steroids

Ottow, Eckhard,Cleve, Arwed,Neef, Guenter,Schwede, Wolfgang

, p. 365 - 370 (1997)

In a highly diastereoselective fashion novel 11β, 17β-diaryl steroids 17 and 18 were synthesized via Birch-type reduction [1] of styrylic precursors 11 and 15. Both precursors were readily available by Suzuki-type coupling reactions [2] of aromatic boroni
