Check Digit Verification of cas no

The CAS Registry Mumber 56579-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,7 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56579-61:
(7*5)+(6*6)+(5*5)+(4*7)+(3*9)+(2*6)+(1*1)=164
164 % 10 = 4
So 56579-61-4 is a valid CAS Registry Number.

Phase-transfer catalysed (PTC) reactions of 1,1-dichloro-2-cyanocyclopropane with nucleophiles. Identification of intermediates

Jonczyk, Andrzej,Kocmierowski, Tomasz,Zdrojewski, Tadeusz

, p. 295 - 299 (2003)

An addition-elimination mechanism for PTC reactions of phenols with 1,1-dichloro-2-cyanocyclopropane (1) is supported by trapping of intermediate cyclopropenes 3 and 5. PTC reactions of 1 with a series of phenols 2a-d, thiophenol (2e), alcohols 2f,g and dithioles 11a,b led to formation of disubstituted cyanocyclopropanes 6a-d, 6e, 6f,g or spiroproducts 12a,b, respectively. Under acidic conditions or thermally, dialkoxycyclopropanes 6f,g or spirane 12a were transformed into alkyl 3-cyanopropionates 10f,g and ketene dithioacetal 13a.
