Check Digit Verification of cas no
The CAS Registry Mumber 5657-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5657-26:
(6*5)+(5*6)+(4*5)+(3*7)+(2*2)+(1*6)=111
111 % 10 = 1
So 5657-26-1 is a valid CAS Registry Number.
