The CAS Registry Mumber 405872-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,8,7 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 405872-80:
(8*4)+(7*0)+(6*5)+(5*8)+(4*7)+(3*2)+(2*8)+(1*0)=152
152 % 10 = 2
So 405872-80-2 is a valid CAS Registry Number.
