Check Digit Verification of cas no
The CAS Registry Mumber 1314-91-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1314-91:
(6*1)+(5*3)+(4*1)+(3*4)+(2*9)+(1*1)=56
56 % 10 = 6
So 1314-91-6 is a valid CAS Registry Number.
