Check Digit Verification of cas no
The CAS Registry Mumber 128807-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,0 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128807-42:
(8*1)+(7*2)+(6*8)+(5*8)+(4*0)+(3*7)+(2*4)+(1*2)=141
141 % 10 = 1
So 128807-42-1 is a valid CAS Registry Number.
