Check Digit Verification of cas no
The CAS Registry Mumber 118209-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,2,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118209-04:
(8*1)+(7*1)+(6*8)+(5*2)+(4*0)+(3*9)+(2*0)+(1*4)=104
104 % 10 = 4
So 118209-04-4 is a valid CAS Registry Number.
