4029-25-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4029-25-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4029-25:
(6*4)+(5*0)+(4*2)+(3*9)+(2*2)+(1*5)=68
68 % 10 = 8
So 4029-25-8 is a valid CAS Registry Number.
