426825-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 426825-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,8,2 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 426825-23:
(8*4)+(7*2)+(6*6)+(5*8)+(4*2)+(3*5)+(2*2)+(1*3)=152
152 % 10 = 2
So 426825-23-2 is a valid CAS Registry Number.
