Check Digit Verification of cas no
The CAS Registry Mumber 19438-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19438-64:
(7*1)+(6*9)+(5*4)+(4*3)+(3*8)+(2*6)+(1*4)=133
133 % 10 = 3
So 19438-64-3 is a valid CAS Registry Number.
