Check Digit Verification of cas no
The CAS Registry Mumber 198759-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,7,5 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198759-65:
(8*1)+(7*9)+(6*8)+(5*7)+(4*5)+(3*9)+(2*6)+(1*5)=218
218 % 10 = 8
So 198759-65-8 is a valid CAS Registry Number.
