Check Digit Verification of cas no
The CAS Registry Mumber 25134-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,3 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25134-21:
(7*2)+(6*5)+(5*1)+(4*3)+(3*4)+(2*2)+(1*1)=78
78 % 10 = 8
So 25134-21-8 is a valid CAS Registry Number.
