Check Digit Verification of cas no

The CAS Registry Mumber 90166-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,6 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90166-03:
(7*9)+(6*0)+(5*1)+(4*6)+(3*6)+(2*0)+(1*3)=113
113 % 10 = 3
So 90166-03-3 is a valid CAS Registry Number.

TRANSFORMED STEROIDS. 133. SYNTHESIS OF 20-DEOXYSTEROIDS WITH A TETRAHYDROPYRAN RING E

Kamernitskii, A. V.,Levi, V. G.,Reshetova, I. G.,Chernoburova, E. I.

, p. 695 - 698 (2007/10/02)

The synthesis of 20-deoxy compounds - the precursors of the steroid pyranols and pyranones synthesized by the authors previously - has been effected from a steroid 20-ketotetrahydropyran by the hydrogenolysis of the corresponding ethylene dithioketal with
