426260-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 426260-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,2,6 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 426260-98:
(8*4)+(7*2)+(6*6)+(5*2)+(4*6)+(3*0)+(2*9)+(1*8)=142
142 % 10 = 2
So 426260-98-2 is a valid CAS Registry Number.
