1373349-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373349-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,3,4 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1373349-13:
(9*1)+(8*3)+(7*7)+(6*3)+(5*3)+(4*4)+(3*9)+(2*1)+(1*3)=163
163 % 10 = 3
So 1373349-13-3 is a valid CAS Registry Number.
