325142-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 325142-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,5,1,4 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 325142-45:
(8*3)+(7*2)+(6*5)+(5*1)+(4*4)+(3*2)+(2*4)+(1*5)=108
108 % 10 = 8
So 325142-45-8 is a valid CAS Registry Number.
