1133972-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1133972-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,9,7 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1133972-22:
(9*1)+(8*1)+(7*3)+(6*3)+(5*9)+(4*7)+(3*2)+(2*2)+(1*2)=141
141 % 10 = 1
So 1133972-22-1 is a valid CAS Registry Number.
