Check Digit Verification of cas no
The CAS Registry Mumber 90071-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,7 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90071-48:
(7*9)+(6*0)+(5*0)+(4*7)+(3*1)+(2*4)+(1*8)=110
110 % 10 = 0
So 90071-48-0 is a valid CAS Registry Number.
