Check Digit Verification of cas no

The CAS Registry Mumber 36130-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,3 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 36130-48:
(7*3)+(6*6)+(5*1)+(4*3)+(3*0)+(2*4)+(1*8)=90
90 % 10 = 0
So 36130-48-0 is a valid CAS Registry Number.

A new synthesis of push-pull pyrroles, their oxidation to stable 3H-pyrroles and an unexpected anellation reaction

Buehrdel, Gunther,Beckert, Rainer,Herzigova, Petra,Petrlikova, Eva,Schuch, Dirk,Birckner, Eckhard,Goerls, Helmar

experimental part, p. 3404 - 3412 (2011/02/28)

A. new synthesis of push-pull pyrroles of type 5 was developed starting from. bis(imidoyl chlorides) 1 and various iminodiacetic acid derivatives 3. The use of appropriate N-trifluoroacetyl residues as protecting/activating group proved to be the method, of choice for the straightforward, preparation of the 3,4-diarylamino-lH-pyrroles 5. When benzothiazole substructures are present in 2,5-position of heterocycles 5, a two-electron oxidation leads to 3H-pyrroles of type 6 in excellent yields. However, in the case of cyano or ester groups, a further oxidative process immediately led to the new 3H-pyrrolo[3,4-b] quinoxalines 7 via intramolecular ring anellation. 2009 Wiley-VCH Verlag GmbH & Co.
