Check Digit Verification of cas no
The CAS Registry Mumber 343306-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,3,0 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 343306-48:
(8*3)+(7*4)+(6*3)+(5*3)+(4*0)+(3*6)+(2*4)+(1*8)=119
119 % 10 = 9
So 343306-48-9 is a valid CAS Registry Number.
