Check Digit Verification of cas no
The CAS Registry Mumber 118974-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118974-19:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*4)+(2*1)+(1*9)=159
159 % 10 = 9
So 118974-19-9 is a valid CAS Registry Number.
