1138772-96-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1138772-96-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,7,7 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1138772-96:
(9*1)+(8*1)+(7*3)+(6*8)+(5*7)+(4*7)+(3*2)+(2*9)+(1*6)=179
179 % 10 = 9
So 1138772-96-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 1587 - 1590 (2009/08/07)
An efficient synthesis of substituted benzotriazoles using an azide-alkyne 1,3-dipolar cycloaddition "click reaction" is described. Key to the procedure is the in situ generation of the reactive aromatic azide and benzyne reaction partners.
