Check Digit Verification of cas no
The CAS Registry Mumber 1334723-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,7,2 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1334723-87:
(9*1)+(8*3)+(7*3)+(6*4)+(5*7)+(4*2)+(3*3)+(2*8)+(1*7)=153
153 % 10 = 3
So 1334723-87-3 is a valid CAS Registry Number.
