136490-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136490-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,9 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136490-96:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*0)+(2*9)+(1*6)=145
145 % 10 = 5
So 136490-96-5 is a valid CAS Registry Number.

Intramolecular aminolysis of 2-aminochalcone epoxides using InBr 3 or BiCl3 as efficient catalysts
Ahmed, Naseem,Kumar, Harendra,Babu, B. Venkata
, p. 567 - 581 (2013/01/15)
In the synthesis of aza-flavanone derivatives, several metal halides were screened for their catalytic activity. Among them, BiCl3 and InBr3 catalyze the ring opening of 2-aminochalcone epoxides followed by intramolecular aminolysis
