Check Digit Verification of cas no
The CAS Registry Mumber 155593-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,9 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155593-00:
(8*1)+(7*5)+(6*5)+(5*5)+(4*9)+(3*3)+(2*0)+(1*0)=143
143 % 10 = 3
So 155593-00-3 is a valid CAS Registry Number.
