Check Digit Verification of cas no
The CAS Registry Mumber 57542-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,4 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57542-74:
(7*5)+(6*7)+(5*5)+(4*4)+(3*2)+(2*7)+(1*4)=142
142 % 10 = 2
So 57542-74-2 is a valid CAS Registry Number.
