Check Digit Verification of cas no
The CAS Registry Mumber 240435-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,4,3 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 240435-90:
(8*2)+(7*4)+(6*0)+(5*4)+(4*3)+(3*5)+(2*9)+(1*0)=109
109 % 10 = 9
So 240435-90-9 is a valid CAS Registry Number.
