Check Digit Verification of cas no
The CAS Registry Mumber 19909-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,0 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19909-64:
(7*1)+(6*9)+(5*9)+(4*0)+(3*9)+(2*6)+(1*4)=149
149 % 10 = 9
So 19909-64-9 is a valid CAS Registry Number.
