Check Digit Verification of cas no
The CAS Registry Mumber 38489-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38489-71:
(7*3)+(6*8)+(5*4)+(4*8)+(3*9)+(2*7)+(1*1)=163
163 % 10 = 3
So 38489-71-3 is a valid CAS Registry Number.
