Check Digit Verification of cas no
The CAS Registry Mumber 444178-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,1,7 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 444178-44:
(8*4)+(7*4)+(6*4)+(5*1)+(4*7)+(3*8)+(2*4)+(1*4)=153
153 % 10 = 3
So 444178-44-3 is a valid CAS Registry Number.
