23130-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23130-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,3 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23130-54:
(7*2)+(6*3)+(5*1)+(4*3)+(3*0)+(2*5)+(1*4)=63
63 % 10 = 3
So 23130-54-3 is a valid CAS Registry Number.

Facile preparation of 2-imino tetrahydrofurans, pyrans and oxepans
Alanine,Fishwick,Szantay Jr.
, p. 6571 - 6572 (2007/10/02)
A simple and convenient route to 2-imino tetrahydrofurans, pyrans and oxepans which utilizes a silver-assisted intramolecular O-alkylation has been developed and produces these novel imidates in good yields and with high stereoselectivity.
