Check Digit Verification of cas no
The CAS Registry Mumber 18853-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18853-40:
(7*1)+(6*8)+(5*8)+(4*5)+(3*3)+(2*4)+(1*0)=132
132 % 10 = 2
So 18853-40-2 is a valid CAS Registry Number.
