The CAS Registry Mumber 523227-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,3,2,2 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 523227-16:
(8*5)+(7*2)+(6*3)+(5*2)+(4*2)+(3*7)+(2*1)+(1*6)=119
119 % 10 = 9
So 523227-16-9 is a valid CAS Registry Number.
