Check Digit Verification of cas no
The CAS Registry Mumber 403705-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,7,0 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 403705-05:
(8*4)+(7*0)+(6*3)+(5*7)+(4*0)+(3*5)+(2*0)+(1*5)=105
105 % 10 = 5
So 403705-05-5 is a valid CAS Registry Number.
