Check Digit Verification of cas no
The CAS Registry Mumber 4089-36-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4089-36:
(6*4)+(5*0)+(4*8)+(3*9)+(2*3)+(1*6)=95
95 % 10 = 5
So 4089-36-5 is a valid CAS Registry Number.

Facile, High-Yield Synthesis of Spiro C-17 Steroidal Oxetan-3'-ones
Pons, Michel,Simons, S. Stoney
, p. 3262 - 3264 (2007/10/02)
The facile, high-yield conversion of C-17 α-keto mesylates of glucocorticoids to spiro C-17 oxetan-3'-ones is described.This reaction, involving treatment with strong base (KOH, NaOMe, or KO-t-Bu) in EtOH or THF, represents a major improvement for the pre
