Check Digit Verification of cas no
The CAS Registry Mumber 1175365-43-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,5,3,6 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1175365-43:
(9*1)+(8*1)+(7*7)+(6*5)+(5*3)+(4*6)+(3*5)+(2*4)+(1*3)=161
161 % 10 = 1
So 1175365-43-1 is a valid CAS Registry Number.
