132872-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132872-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,7 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132872-64:
(8*1)+(7*3)+(6*2)+(5*8)+(4*7)+(3*2)+(2*6)+(1*4)=131
131 % 10 = 1
So 132872-64-1 is a valid CAS Registry Number.

Bromine, N-bromosuccinimide and sulphur induced isomerizations in the hopane series
Bisseret, Philippe,Rohmer, Michel
, p. 7445 - 7448 (2007/10/02)
When reacted with bromine, N-bromosuccinimide or molten sulphur, triterpenoids of the 17β(H),21β(H)-hopane series were converted into their 17α(H),21β(H) and 17β(H),21α(H) isomers of geochemical significance.
