5Check Digit Verification of cas no
The CAS Registry Mumber 12262-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.Calculate Digit Verification of CAS Registry Number 12262-39:
(7*1)+(6*2)+(5*2)+(4*6)+(3*2)+(2*3)+(1*9)=74
74 % 10 = 4
So 12262-39-4 is a valid CAS Registry Number.
