Check Digit Verification of cas no
The CAS Registry Mumber 24168-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,1,6 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 24168-70:
(7*2)+(6*4)+(5*1)+(4*6)+(3*8)+(2*7)+(1*0)=105
105 % 10 = 5
So 24168-70-5 is a valid CAS Registry Number.
