Check Digit Verification of cas no

The CAS Registry Mumber 93206-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,0 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93206-71:
(7*9)+(6*3)+(5*2)+(4*0)+(3*6)+(2*7)+(1*1)=124
124 % 10 = 4
So 93206-71-4 is a valid CAS Registry Number.

Synthesis of 17-(isocyanotosylmethylene) steroids: precursors to pregnane derivatives

Leusen, Daan van,Leusen, Albert M. van

, p. 393 - 401 (2007/10/02)

The synthesis is described of a series of twenty 17-(isocyanotosylmethylene) steroids 5 from 17-oxo steroids and 4-tolylsulfonylmethyl isocyanide (TosMIC).Furthermore, nine analogous 17-(isocyanosulfonylmethylene) steroids (15-21a) have been prepared usin
