Check Digit Verification of cas no
The CAS Registry Mumber 405290-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,2,9 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 405290-56:
(8*4)+(7*0)+(6*5)+(5*2)+(4*9)+(3*0)+(2*5)+(1*6)=124
124 % 10 = 4
So 405290-56-4 is a valid CAS Registry Number.
