81518-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81518-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,1 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81518-09:
(7*8)+(6*1)+(5*5)+(4*1)+(3*8)+(2*0)+(1*9)=124
124 % 10 = 4
So 81518-09-4 is a valid CAS Registry Number.
