426261-00-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 426261-00-9 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 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 426261-00:
(8*4)+(7*2)+(6*6)+(5*2)+(4*6)+(3*1)+(2*0)+(1*0)=119
119 % 10 = 9
So 426261-00-9 is a valid CAS Registry Number.
