402713-75-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402713-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,7,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 402713-75:
(8*4)+(7*0)+(6*2)+(5*7)+(4*1)+(3*3)+(2*7)+(1*5)=111
111 % 10 = 1
So 402713-75-1 is a valid CAS Registry Number.

On catalytic hydrogenation of Δ9-steroids (e.g. 3β-hydroxy-5-methyl-19-nor-5β-androst-9-en-17-one), four isomers were formed: 9α,10α-, 9α,10β-, 9β,10α- and 9β,10β-adducts. The product distribution was affected by the nature of the C-3 substitue
