Check Digit Verification of cas no
The CAS Registry Mumber 130161-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,6 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130161-53:
(8*1)+(7*3)+(6*0)+(5*1)+(4*6)+(3*1)+(2*5)+(1*3)=74
74 % 10 = 4
So 130161-53-4 is a valid CAS Registry Number.
