Check Digit Verification of cas no
The CAS Registry Mumber 40398-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,9 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40398-02:
(7*4)+(6*0)+(5*3)+(4*9)+(3*8)+(2*0)+(1*2)=105
105 % 10 = 5
So 40398-02-5 is a valid CAS Registry Number.

, (2008/06/13)
Two procedures are described that can be used to prepare polyhalogenated phenyl isocyanates (2,4,6-trichloro,2,3,5,6-tetrachloro, pentachloro, 2,4,6-tribromo and 2,4,6-trifluoro derivatives) from the corresponding anilines in good yields (95-99%) with sma
