Check Digit Verification of cas no
The CAS Registry Mumber 498563-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,6 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 498563-50:
(8*4)+(7*9)+(6*8)+(5*5)+(4*6)+(3*3)+(2*5)+(1*0)=211
211 % 10 = 1
So 498563-50-1 is a valid CAS Registry Number.
