81482-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81482-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,8 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81482-72:
(7*8)+(6*1)+(5*4)+(4*8)+(3*2)+(2*7)+(1*2)=136
136 % 10 = 6
So 81482-72-6 is a valid CAS Registry Number.
