Check Digit Verification of cas no

The CAS Registry Mumber 201467-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,4,6 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201467-42:
(8*2)+(7*0)+(6*1)+(5*4)+(4*6)+(3*7)+(2*4)+(1*2)=97
97 % 10 = 7
So 201467-42-7 is a valid CAS Registry Number.

Synthesis of 11,13-bridged progestational steroids

Broess,Groen,Hamersma

, p. 2925 - 2928 (1997)

11,13-Ethanopregnanes were prepared to assess the influence of the bending of the steroid skeleton on progestagenic activity. It was demonstrated that, contrary to previous assumptions, upward bending of the A ring has little overall effect on the activity.
