Check Digit Verification of cas no
The CAS Registry Mumber 4404-39-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4404-39:
(6*4)+(5*4)+(4*0)+(3*4)+(2*3)+(1*9)=71
71 % 10 = 1
So 4404-39-1 is a valid CAS Registry Number.
