862197-80-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862197-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,1,9 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 862197-80:
(8*8)+(7*6)+(6*2)+(5*1)+(4*9)+(3*7)+(2*8)+(1*0)=196
196 % 10 = 6
So 862197-80-6 is a valid CAS Registry Number.
