Check Digit Verification of cas no

The CAS Registry Mumber 51267-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,6 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51267-64:
(7*5)+(6*1)+(5*2)+(4*6)+(3*7)+(2*6)+(1*4)=112
112 % 10 = 2
So 51267-64-2 is a valid CAS Registry Number.

Synthesis of 5,17-dihydroxy-5α,17α,-19-norpregn-20-yn-3-one, a major photodegradation product of norethindrone

Cooper

, p. 459 - 464 (1988)

A convenient synthesis of 5,17-dihydroxy-5α,17α-19-norpregn-20-yn-3-one in multigram quantities from norethindrone is reported. Confirmation of the structural assignment of this major photodegradation product of norethindrone is thus made.
