130256-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130256-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,5 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130256-21:
(8*1)+(7*3)+(6*0)+(5*2)+(4*5)+(3*6)+(2*2)+(1*1)=82
82 % 10 = 2
So 130256-21-2 is a valid CAS Registry Number.

Katritzky, Alan R.,Rao, M. Suresh Chander
, p. 663 - 666 (2007/10/02)
N-Hydroxybenzamides 1 react with hydroxymethylbenzotriazole (2) to give (benzotriazol-1-yl)methyl derivatives 3.These are converted by aryl Grignard reagents into acylic N-(α-hydroxybenzyl)benzamides 6.
