Check Digit Verification of cas no
The CAS Registry Mumber 161316-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,3,1 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 161316-50:
(8*1)+(7*6)+(6*1)+(5*3)+(4*1)+(3*6)+(2*5)+(1*0)=103
103 % 10 = 3
So 161316-50-3 is a valid CAS Registry Number.
