1133972-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1133972-16-3 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, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1133972-16:
(9*1)+(8*1)+(7*3)+(6*3)+(5*9)+(4*7)+(3*2)+(2*1)+(1*6)=143
143 % 10 = 3
So 1133972-16-3 is a valid CAS Registry Number.
