118891-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118891-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118891-85:
(8*1)+(7*1)+(6*8)+(5*8)+(4*9)+(3*1)+(2*8)+(1*5)=163
163 % 10 = 3
So 118891-85-3 is a valid CAS Registry Number.
