Check Digit Verification of cas no
The CAS Registry Mumber 128071-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,7 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128071-03:
(8*1)+(7*2)+(6*8)+(5*0)+(4*7)+(3*1)+(2*0)+(1*3)=104
104 % 10 = 4
So 128071-03-4 is a valid CAS Registry Number.
