Check Digit Verification of cas no
The CAS Registry Mumber 20497-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20497-90:
(7*2)+(6*0)+(5*4)+(4*9)+(3*7)+(2*9)+(1*0)=109
109 % 10 = 9
So 20497-90-9 is a valid CAS Registry Number.
