82294-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82294-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,9 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82294-05:
(7*8)+(6*2)+(5*2)+(4*9)+(3*4)+(2*0)+(1*5)=131
131 % 10 = 1
So 82294-05-1 is a valid CAS Registry Number.
