Check Digit Verification of cas no
The CAS Registry Mumber 1155311-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,3,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1155311-67:
(9*1)+(8*1)+(7*5)+(6*5)+(5*3)+(4*1)+(3*1)+(2*6)+(1*7)=123
123 % 10 = 3
So 1155311-67-3 is a valid CAS Registry Number.
