Check Digit Verification of cas no
The CAS Registry Mumber 804552-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,4,5,5 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 804552-05:
(8*8)+(7*0)+(6*4)+(5*5)+(4*5)+(3*2)+(2*0)+(1*5)=144
144 % 10 = 4
So 804552-05-4 is a valid CAS Registry Number.
