Check Digit Verification of cas no
The CAS Registry Mumber 247226-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,2,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 247226-18:
(8*2)+(7*4)+(6*7)+(5*2)+(4*2)+(3*6)+(2*1)+(1*8)=132
132 % 10 = 2
So 247226-18-2 is a valid CAS Registry Number.
