13969-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13969-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13969-02:
(7*1)+(6*3)+(5*9)+(4*6)+(3*9)+(2*0)+(1*2)=123
123 % 10 = 3
So 13969-02-3 is a valid CAS Registry Number.
