13468-92-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13468-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,6 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13468-92:
(7*1)+(6*3)+(5*4)+(4*6)+(3*8)+(2*9)+(1*2)=113
113 % 10 = 3
So 13468-92-3 is a valid CAS Registry Number.
