Check Digit Verification of cas no
The CAS Registry Mumber 204074-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,0,7 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 204074-54:
(8*2)+(7*0)+(6*4)+(5*0)+(4*7)+(3*4)+(2*5)+(1*4)=94
94 % 10 = 4
So 204074-54-4 is a valid CAS Registry Number.
