Check Digit Verification of cas no
The CAS Registry Mumber 12392-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,3,9 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12392-64:
(7*1)+(6*2)+(5*3)+(4*9)+(3*2)+(2*6)+(1*4)=92
92 % 10 = 2
So 12392-64-2 is a valid CAS Registry Number.
