Check Digit Verification of cas no
The CAS Registry Mumber 13069-04-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,6 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13069-04:
(7*1)+(6*3)+(5*0)+(4*6)+(3*9)+(2*0)+(1*4)=80
80 % 10 = 0
So 13069-04-0 is a valid CAS Registry Number.
