25342-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25342-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,4 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25342-82:
(7*2)+(6*5)+(5*3)+(4*4)+(3*2)+(2*8)+(1*2)=99
99 % 10 = 9
So 25342-82-9 is a valid CAS Registry Number.
