56948-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56948-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,4 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56948-70:
(7*5)+(6*6)+(5*9)+(4*4)+(3*8)+(2*7)+(1*0)=170
170 % 10 = 0
So 56948-70-0 is a valid CAS Registry Number.

SYNTHESIS OF SOME STEROID SPIN LABELS
Dodd, J. R.,Mathew, Abraham E.
, p. 241 - 248 (2007/10/02)
An improved synthesis of spin-labeled cortisol, cortisone, and testosterone using N,N'-cyclohexylcarbodiimide (DCC) is reported.The spin labeled steroids are shown to result from the esterification at the most reactive C(21) and C(17) hydroxyl groups.A mi
