Check Digit Verification of cas no
The CAS Registry Mumber 44804-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,4,8,0 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 44804-84:
(7*4)+(6*4)+(5*8)+(4*0)+(3*4)+(2*8)+(1*4)=124
124 % 10 = 4
So 44804-84-4 is a valid CAS Registry Number.
