142832-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142832-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,3 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142832-37:
(8*1)+(7*4)+(6*2)+(5*8)+(4*3)+(3*2)+(2*3)+(1*7)=119
119 % 10 = 9
So 142832-37-9 is a valid CAS Registry Number.

The relatively low temperature (200°C) intramolecular ene reaction of 4,5-seco-5β-cholest-3-en-5-ol-6-one followed by in situ rearrangement affords 3-methyl-B-nor-5β-cholest-2-en-4-one and 5-hydroxy-5β-cholestan-6-one and supports the view that 3β-methyl-
