31118-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31118-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,1 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31118-73:
(7*3)+(6*1)+(5*1)+(4*1)+(3*8)+(2*7)+(1*3)=77
77 % 10 = 7
So 31118-73-7 is a valid CAS Registry Number.
