Check Digit Verification of cas no
The CAS Registry Mumber 319916-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,9,9,1 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 319916-44:
(8*3)+(7*1)+(6*9)+(5*9)+(4*1)+(3*6)+(2*4)+(1*4)=164
164 % 10 = 4
So 319916-44-4 is a valid CAS Registry Number.
