Check Digit Verification of cas no
The CAS Registry Mumber 75263-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,6 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75263-19:
(7*7)+(6*5)+(5*2)+(4*6)+(3*3)+(2*1)+(1*9)=133
133 % 10 = 3
So 75263-19-3 is a valid CAS Registry Number.
