118617-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118617-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,1 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118617-19:
(8*1)+(7*1)+(6*8)+(5*6)+(4*1)+(3*7)+(2*1)+(1*9)=129
129 % 10 = 9
So 118617-19-9 is a valid CAS Registry Number.
