325142-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 325142-54-9 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, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 325142-54:
(8*3)+(7*2)+(6*5)+(5*1)+(4*4)+(3*2)+(2*5)+(1*4)=109
109 % 10 = 9
So 325142-54-9 is a valid CAS Registry Number.
