Check Digit Verification of cas no
The CAS Registry Mumber 1256-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1256-83:
(6*1)+(5*2)+(4*5)+(3*6)+(2*8)+(1*3)=73
73 % 10 = 3
So 1256-83-3 is a valid CAS Registry Number.

Thermolytic Transformation of Steroidal Nitroimines
Ahmad, M. S.,Raza, S. K.
, p. 259 - 260 (2007/10/02)
Thermolysis of 6-nitroimino-5α-cholestan-3β-yl acetate (I), 6-nitroimino-5α-cholestane (VII) and 7-nitroiminocholest-5-en-3β-yl chloride (XII) in refluxing xylene affords a mixture of products in the case of I and VII and a chlorine-free product in the case of XII.The known products have been characterized by direct comparison while unknown products by elemental analyses and spectral data.
