Check Digit Verification of cas no
The CAS Registry Mumber 503056-28-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 503056-28:
(8*5)+(7*0)+(6*3)+(5*0)+(4*5)+(3*6)+(2*2)+(1*8)=108
108 % 10 = 8
So 503056-28-8 is a valid CAS Registry Number.
