84109-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84109-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84109-71:
(7*8)+(6*4)+(5*1)+(4*0)+(3*9)+(2*7)+(1*1)=127
127 % 10 = 7
So 84109-71-7 is a valid CAS Registry Number.
