Check Digit Verification of cas no
The CAS Registry Mumber 666723-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,7,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 666723-13:
(8*6)+(7*6)+(6*6)+(5*7)+(4*2)+(3*3)+(2*1)+(1*3)=183
183 % 10 = 3
So 666723-13-3 is a valid CAS Registry Number.
