Check Digit Verification of cas no
The CAS Registry Mumber 1159195-67-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,1,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1159195-67:
(9*1)+(8*1)+(7*5)+(6*9)+(5*1)+(4*9)+(3*5)+(2*6)+(1*7)=181
181 % 10 = 1
So 1159195-67-1 is a valid CAS Registry Number.
