Check Digit Verification of cas no
The CAS Registry Mumber 6408-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6408-99:
(6*6)+(5*4)+(4*0)+(3*8)+(2*9)+(1*9)=107
107 % 10 = 7
So 6408-99-7 is a valid CAS Registry Number.
