1431367-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431367-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,3,6 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1431367-13:
(9*1)+(8*4)+(7*3)+(6*1)+(5*3)+(4*6)+(3*7)+(2*1)+(1*3)=133
133 % 10 = 3
So 1431367-13-3 is a valid CAS Registry Number.
