268204-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 268204-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,8,2,0 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 268204-20:
(8*2)+(7*6)+(6*8)+(5*2)+(4*0)+(3*4)+(2*2)+(1*0)=132
132 % 10 = 2
So 268204-20-2 is a valid CAS Registry Number.
