148257-97-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148257-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,2,5 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 148257-97:
(8*1)+(7*4)+(6*8)+(5*2)+(4*5)+(3*7)+(2*9)+(1*7)=160
160 % 10 = 0
So 148257-97-0 is a valid CAS Registry Number.

Synthesis of annularly functionalised BINOL-based chiral cyclophanes
Srisailas, Muthialu,Rajakumar, Perumal
, p. 671 - 674 (2007/10/03)
Chiral cyclophanes with annular functionality were synthesised by coupling carbonyl dibromides with (S)-BINOL. Semi-empirical calculations by MOPAC (PM3) were also performed on the cyclophanes prepared to view their cavity sizes.
