Check Digit Verification of cas no
The CAS Registry Mumber 13664-80-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,6 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13664-80:
(7*1)+(6*3)+(5*6)+(4*6)+(3*4)+(2*8)+(1*0)=107
107 % 10 = 7
So 13664-80-7 is a valid CAS Registry Number.
