Check Digit Verification of cas no
The CAS Registry Mumber 80316-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,1 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.Calculate Digit Verification of CAS Registry Number 80316-29:
(7*8)+(6*0)+(5*3)+(4*1)+(3*6)+(2*2)+(1*9)=106
106 % 10 = 6
So 80316-29-6 is a valid CAS Registry Number.
