Check Digit Verification of cas no
The CAS Registry Mumber 1165931-67-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,5,9,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1165931-67:
(9*1)+(8*1)+(7*6)+(6*5)+(5*9)+(4*3)+(3*1)+(2*6)+(1*7)=168
168 % 10 = 8
So 1165931-67-8 is a valid CAS Registry Number.
