The CAS Registry Mumber 138723-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,2 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138723-04:
(8*1)+(7*3)+(6*8)+(5*7)+(4*2)+(3*3)+(2*0)+(1*4)=133
133 % 10 = 3
So 138723-04-3 is a valid CAS Registry Number.
