31949-41-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31949-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31949-41:
(7*3)+(6*1)+(5*9)+(4*4)+(3*9)+(2*4)+(1*1)=124
124 % 10 = 4
So 31949-41-4 is a valid CAS Registry Number.

Synthesis of anabaseine and anabasine derivatives: Structural modifications of possible nicotinic agonists

Sobarzo-Sanchez, Eduardo,Castedo, Luis,De La Fuente, Julio R.

, p. 1331 - 1338 (2007)

Coupling nicotinoyl chloride with 3,4-dimetoxyphenethylamine under Bischler-Napieralski cyclization afforded the isoquinoline (4) in good yield. This latter was used as starting material to obtain with only hydrobromic acid a product with demethylation at

Diazaestrones and analogs. II. Structural modifications of succinimidoethyldihydroisoquinoline, heterosteroid precursor, to establish structure-analgesic activity relationship

Hocquaux,Viel,Brunaud,et al.

, p. 331 - 338 (2007/10/02)

β-1-(succinimidoethyl)-6,7-dimethoxydihydroisoquinoline having exihibited a stronger analgesic activity than the methylester of 2-methoxy-8,13-diazaestrone, its structure has been systematically modified in view of establishing a relation between structur
