113861-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113861-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,6 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 113861-04:
(8*1)+(7*1)+(6*3)+(5*8)+(4*6)+(3*1)+(2*0)+(1*4)=104
104 % 10 = 4
So 113861-04-4 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.
