75561-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75561-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,6 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75561-01:
(7*7)+(6*5)+(5*5)+(4*6)+(3*1)+(2*0)+(1*1)=132
132 % 10 = 2
So 75561-01-2 is a valid CAS Registry Number.

The Solvolysis of 4β-Hydroxy-3β-p-tolylsulphonyloxyandrost-5-enes
Hanson, James R.,Wadsworth, Harry J.
, p. 933 - 937 (2007/10/02)
The solvolysis of 3β-p-tolylsulphonyloxyandrost-5-enes in acetic acid containing sodium acetate, is retarded by the presence of a 4β-acetoxy- or hydroxy-group.The products of solvolysis include the A-nor-3-formyl-steroids except in the presence of a 7-ketone.
