82417-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82417-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,1 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82417-72:
(7*8)+(6*2)+(5*4)+(4*1)+(3*7)+(2*7)+(1*2)=129
129 % 10 = 9
So 82417-72-9 is a valid CAS Registry Number.
