25038-86-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25038-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,3 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25038-86:
(7*2)+(6*5)+(5*0)+(4*3)+(3*8)+(2*8)+(1*6)=102
102 % 10 = 2
So 25038-86-2 is a valid CAS Registry Number.
