Check Digit Verification of cas no
The CAS Registry Mumber 146384-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,8 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146384-40:
(8*1)+(7*4)+(6*6)+(5*3)+(4*8)+(3*4)+(2*4)+(1*0)=139
139 % 10 = 9
So 146384-40-9 is a valid CAS Registry Number.
