109936-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109936-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,3 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109936-48:
(8*1)+(7*0)+(6*9)+(5*9)+(4*3)+(3*6)+(2*4)+(1*8)=153
153 % 10 = 3
So 109936-48-3 is a valid CAS Registry Number.

supporting information; experimental part, p. 2400 - 2404 (2009/02/02)
N-(4-Arylazobenzoyl)-1H-benzotriazoles 3 react with amino acids 4 and amines 6 to give azo-dye labeled amino acids (5a-m) and amines (7a-n) in high yields (74-100%) with retention of chirality.
