Check Digit Verification of cas no
The CAS Registry Mumber 99141-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,4 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99141-18:
(7*9)+(6*9)+(5*1)+(4*4)+(3*1)+(2*1)+(1*8)=151
151 % 10 = 1
So 99141-18-1 is a valid CAS Registry Number.
