Check Digit Verification of cas no
The CAS Registry Mumber 5438-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,3 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5438-79:
(6*5)+(5*4)+(4*3)+(3*8)+(2*7)+(1*9)=109
109 % 10 = 9
So 5438-79-9 is a valid CAS Registry Number.
