957473-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 957473-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,4,7 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 957473-22:
(8*9)+(7*5)+(6*7)+(5*4)+(4*7)+(3*3)+(2*2)+(1*2)=212
212 % 10 = 2
So 957473-22-2 is a valid CAS Registry Number.

This paper describes our attempts to synthesize inherently chiral heteroatom-bridged calixaromatics. Based on a stepwise fragment-coupling approach using a chiral 3,5-dihydroxybenzamide or benzoate, 2,4-dihydroxyacetophenone, and cyanuric chloride as reac
