Check Digit Verification of cas no
The CAS Registry Mumber 790674-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,0,6,7 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 790674-48:
(8*7)+(7*9)+(6*0)+(5*6)+(4*7)+(3*4)+(2*4)+(1*8)=205
205 % 10 = 5
So 790674-48-5 is a valid CAS Registry Number.

Synthesis of enantiomerically pure dissymmetric 2,2′-disubstituted 9,9′-spirobifluorenes

, p. 1991 - 2001 (2007/10/03)
Racemic dissymmetric 2,2′-dihydroxy-9,9′-spirobifluorene was prepared and resolved by clathrate formation with (R,R)-(+)-2,3-dimethoxy-N,N, N′,N′-tetracyclohexylsuccindiamide, giving rise to both enantiomers in very good yields. The absolute stereochemistry of the resolved material could be assigned by an X-ray structure analysis of single crystals of the clathrate. Enantiomerically pure diols could be transformed into the corresponding ditriflates, which were then used as starting materials in different cross-coupling procedures to provide a number of new enantiomerically pure spiro compounds bearing versatile functional groups suitable for further elaboration, as demonstrated by some examples.
