1263293-03-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1263293-03-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,2,9 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263293-03:
(9*1)+(8*2)+(7*6)+(6*3)+(5*2)+(4*9)+(3*3)+(2*0)+(1*3)=143
143 % 10 = 3
So 1263293-03-3 is a valid CAS Registry Number.
