61449-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61449-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,4 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61449-82:
(7*6)+(6*1)+(5*4)+(4*4)+(3*9)+(2*8)+(1*2)=129
129 % 10 = 9
So 61449-82-9 is a valid CAS Registry Number.
