546-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 546-99-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 546-99:
(5*5)+(4*4)+(3*6)+(2*9)+(1*9)=86
86 % 10 = 6
So 546-99-6 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.
