The CAS Registry Mumber 1334666-59-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,6,6 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334666-59:
(9*1)+(8*3)+(7*3)+(6*4)+(5*6)+(4*6)+(3*6)+(2*5)+(1*9)=169
169 % 10 = 9
So 1334666-59-9 is a valid CAS Registry Number.
