84247-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84247-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,4 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84247-39:
(7*8)+(6*4)+(5*2)+(4*4)+(3*7)+(2*3)+(1*9)=142
142 % 10 = 2
So 84247-39-2 is a valid CAS Registry Number.
