Check Digit Verification of cas no
The CAS Registry Mumber 439611-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,1 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 439611-05:
(8*4)+(7*3)+(6*9)+(5*6)+(4*1)+(3*1)+(2*0)+(1*5)=149
149 % 10 = 9
So 439611-05-9 is a valid CAS Registry Number.
