81282-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81282-93-1 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, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81282-93:
(7*8)+(6*1)+(5*2)+(4*8)+(3*2)+(2*9)+(1*3)=131
131 % 10 = 1
So 81282-93-1 is a valid CAS Registry Number.
