Check Digit Verification of cas no
The CAS Registry Mumber 60389-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,3,8 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 60389-48:
(7*6)+(6*0)+(5*3)+(4*8)+(3*9)+(2*4)+(1*8)=132
132 % 10 = 2
So 60389-48-2 is a valid CAS Registry Number.
