426210-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 426210-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,2,1 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 426210-89:
(8*4)+(7*2)+(6*6)+(5*2)+(4*1)+(3*0)+(2*8)+(1*9)=121
121 % 10 = 1
So 426210-89-1 is a valid CAS Registry Number.

, p. 171 - 173 (2007/10/03)
The "commercially available chirality" of the binaphthyl units and the efficiency of the coupling reactions were crucial to the synthesis of double-helical alkynyl cylophanes 1 in enantiopure form. The unique properties of these molecules have been unambi
