862209-51-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862209-51-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,2,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 862209-51:
(8*8)+(7*6)+(6*2)+(5*2)+(4*0)+(3*9)+(2*5)+(1*1)=166
166 % 10 = 6
So 862209-51-6 is a valid CAS Registry Number.
