Check Digit Verification of cas no
The CAS Registry Mumber 104969-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104969-64:
(8*1)+(7*0)+(6*4)+(5*9)+(4*6)+(3*9)+(2*6)+(1*4)=144
144 % 10 = 4
So 104969-64-4 is a valid CAS Registry Number.
