Check Digit Verification of cas no
The CAS Registry Mumber 128561-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,6 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128561-99:
(8*1)+(7*2)+(6*8)+(5*5)+(4*6)+(3*1)+(2*9)+(1*9)=149
149 % 10 = 9
So 128561-99-9 is a valid CAS Registry Number.
