Check Digit Verification of cas no

The CAS Registry Mumber 158749-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,7,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158749-41:
(8*1)+(7*5)+(6*8)+(5*7)+(4*4)+(3*9)+(2*4)+(1*1)=178
178 % 10 = 8
So 158749-41-8 is a valid CAS Registry Number.

Effective chemiluminogenic systems based on acridinium esters bearing substituents of various electronic and steric properties

Zadykowicz, Beata,Czechowska, Justyna,Ozóg, Agnieszka,Renkevich, Anton,Krzymiński, Karol

, p. 652 - 668 (2015)

A series of 10-methyl-9-(phenoxycarbonyl)acridinium trifluoromethanesulfonates (XAEs), bearing substituents of various characteristics in the lateral benzene ring (2-halogen, 2,6-dihalogen, 2-trifluoromethyl, 2-nitro, 2-methoxy, 3-halogen and 4-halogen) w

Synthesis and properties of new luminescent 10-carboxymethylacridinium derivatives

Sato, Naofumi

, p. 8519 - 8522 (2007/10/03)

A novel method was developed to synthesize acridinium esters having a binding functional group at N-10. An acridine ester having steric hindrance is synthesized quickly, with excellent yields, using dimethylaminopyridine as a catalyst. Alkylation of the N-10 on the acridine ring proceeds using the trifluoromethanesulfonic acid ester under mild conditions. Deprotection of the benzyl ester using acid thus enables simple, high-yield synthesis for acridinium compounds with a binding functional group at N-10.
