84261-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84261-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,6 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84261-44:
(7*8)+(6*4)+(5*2)+(4*6)+(3*1)+(2*4)+(1*4)=129
129 % 10 = 9
So 84261-44-9 is a valid CAS Registry Number.
