Check Digit Verification of cas no
The CAS Registry Mumber 25677-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25677-40:
(7*2)+(6*5)+(5*6)+(4*7)+(3*7)+(2*4)+(1*0)=131
131 % 10 = 1
So 25677-40-1 is a valid CAS Registry Number.
