Check Digit Verification of cas no
The CAS Registry Mumber 25810-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,1 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25810-70:
(7*2)+(6*5)+(5*8)+(4*1)+(3*0)+(2*7)+(1*0)=102
102 % 10 = 2
So 25810-70-2 is a valid CAS Registry Number.
