Check Digit Verification of cas no
The CAS Registry Mumber 51971-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,7 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51971-64:
(7*5)+(6*1)+(5*9)+(4*7)+(3*1)+(2*6)+(1*4)=133
133 % 10 = 3
So 51971-64-3 is a valid CAS Registry Number.
