Check Digit Verification of cas no

The CAS Registry Mumber 42444-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,4 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42444-30:
(7*4)+(6*2)+(5*4)+(4*4)+(3*4)+(2*3)+(1*0)=94
94 % 10 = 4
So 42444-30-4 is a valid CAS Registry Number.

Cycloadditions of nitrile oxides to the highly reactive N-acyl-2-oxa-3- azanorborn-5-enes afford versatile cycloadducts and a convenient entry to highly functionalized derivatives

Quadrelli, Paolo,Mella, Mariella,Paganoni, Pierangela,Caramella, Pierluigi

, p. 2613 - 2620 (2007/10/03)

N-Acyl-2-oxa-3-azanorborn-5-enes are highly reactive dipolarophiles in cycloadditions with nitrile oxides. The cycloadducts can be easily elaborated to various functionalized structures that are not directly accessible by 1,3- dipolar cycloadditions.
