Check Digit Verification of cas no

The CAS Registry Mumber 270568-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,5,6 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 270568-80:
(8*2)+(7*7)+(6*0)+(5*5)+(4*6)+(3*8)+(2*8)+(1*0)=154
154 % 10 = 4
So 270568-80-4 is a valid CAS Registry Number.

Synthesis and structure-activity studies of 8α- and 9β-analogues of 14,17-ethanoestradiol

Bull, James R.,De Koning, Pieter D.

, p. 1003 - 1013 (2000)

Synthetic routes to the title compounds are described, commencing with readily available 19-norsteroid precursors. The reaction of 3-methoxy-8α-estra-1,3,5(10),14,16-pentaen-17-yl acetate 3 with phenyl vinyl sulfone at 150 °C proceeded in high yield, but
