Check Digit Verification of cas no
The CAS Registry Mumber 808162-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,1,6 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 808162-99:
(8*8)+(7*0)+(6*8)+(5*1)+(4*6)+(3*2)+(2*9)+(1*9)=174
174 % 10 = 4
So 808162-99-4 is a valid CAS Registry Number.
