Check Digit Verification of cas no
The CAS Registry Mumber 199858-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 199858-09:
(8*1)+(7*9)+(6*9)+(5*8)+(4*5)+(3*8)+(2*0)+(1*9)=218
218 % 10 = 8
So 199858-09-8 is a valid CAS Registry Number.
