84201-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84201-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84201-56:
(7*8)+(6*4)+(5*2)+(4*0)+(3*1)+(2*5)+(1*6)=109
109 % 10 = 9
So 84201-56-9 is a valid CAS Registry Number.
