Check Digit Verification of cas no

The CAS Registry Mumber 5522-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5522-64:
(6*5)+(5*5)+(4*2)+(3*2)+(2*6)+(1*4)=85
85 % 10 = 5
So 5522-64-5 is a valid CAS Registry Number.

Synthesis of a linear α-hydroxymethyl-pentapyrrole derivative and its cyclization to uroporphyrinogens

Okada, Kunisuke,Takakura, Hiroyuki,Nomura, Keishi,Saburi, Kiyoshi

, p. 2915 - 2918 (2000)

A linear pentapyrrole bearing α-hydroxymeythyl group in the terminal was synthesized by the stepwise coupling of α-free pyrrole with azafulvenium ion 6. When it was treated with a catalytic amount of p-toluensulfonic acid under anaerobic condition, followed by aerial oxidation of the products, a statistical mixture of uroporphyrin I-IV octamethyl esters was obtained. It is proposed that this transformation proceeds through a spiro-pyrrolenine as a key intermediate. (C) 2000 Elsevier Science Ltd.
