Check Digit Verification of cas no

The CAS Registry Mumber 137725-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,2 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137725-35:
(8*1)+(7*3)+(6*7)+(5*7)+(4*2)+(3*5)+(2*3)+(1*5)=140
140 % 10 = 0
So 137725-35-0 is a valid CAS Registry Number.

Chemoselective reactioms of 14,17α-bis(hydroxymethyl)-3-methoxyestra-1,3,5(10)-trien-17β-ol. Synthesis of novel 14,17-hetero-bridged 19-norsteroids

Bull, James R.,Steer, Lynne H.

, p. 7377 - 7402 (2007/10/02)

Chemoselective differentiation of the primary hydroxy groups in 14,17α-bis(hydroxymethyl)-3-methoxyestra-1,3,5(10)-trien-17β-ol (2) has been investigated in a series of reactions which lead inter alia to novel 14,17-hetero-bridged steroid hormone analogue
