Check Digit Verification of cas no

The CAS Registry Mumber 109806-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,0 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109806-78:
(8*1)+(7*0)+(6*9)+(5*8)+(4*0)+(3*6)+(2*7)+(1*8)=142
142 % 10 = 2
So 109806-78-2 is a valid CAS Registry Number.

A NEW AND CONVENIENT SYNTHESIS OF PROTOBERBERINE ALKALOIDS: (+/-)-TETRAHYDROPALMATINE, (+/-)-SINACTINE, (+/-)-CANADINE AND-)-STYLOPINE

Yasuda, Shingo,Hirasawa, Taeko,Hanaoka, Miyoji

, p. 2399 - 2402 (1987)

2,3,9,10-Tetraoxygenated protoberberine alkaloids (14) were efficiently synthesized from the readily available benzaldehyde (2 or 10) via the benzylphenethylamines (11) and 2-phenethylisoquinolin-3-ones (12 or 13).

Synthesis and antihyperglycemic evaluation of various protoberberine derivatives

Bian, Xiaoli,He, Langchong,Yang, Guangde

, p. 1380 - 1383 (2007/10/03)

Various berberine derivatives (2-17) were synthesized and their antihyperglycemic activities were evaluated in a model of β-cell-membrane chromatography and a model of alloxan-induced diabetes mice. The results indicated that compounds 5 and 14 exhibited antihyperglycemic activity. Their structure-activity relationships were discussed.
