The CAS Registry Mumber 402-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 402-40:
(5*4)+(4*0)+(3*2)+(2*4)+(1*0)=34
34 % 10 = 4
So 402-40-4 is a valid CAS Registry Number.
