81282-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81282-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,8 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81282-83:
(7*8)+(6*1)+(5*2)+(4*8)+(3*2)+(2*8)+(1*3)=129
129 % 10 = 9
So 81282-83-9 is a valid CAS Registry Number.
