Check Digit Verification of cas no
The CAS Registry Mumber 54093-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54093-92:
(7*5)+(6*4)+(5*0)+(4*9)+(3*3)+(2*9)+(1*2)=124
124 % 10 = 4
So 54093-92-4 is a valid CAS Registry Number.
