Check Digit Verification of cas no
The CAS Registry Mumber 80685-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80685-64:
(7*8)+(6*0)+(5*6)+(4*8)+(3*5)+(2*6)+(1*4)=149
149 % 10 = 9
So 80685-64-9 is a valid CAS Registry Number.
