Check Digit Verification of cas no

The CAS Registry Mumber 900019-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,0,1 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 900019-46:
(8*9)+(7*0)+(6*0)+(5*0)+(4*1)+(3*9)+(2*4)+(1*6)=117
117 % 10 = 7
So 900019-46-7 is a valid CAS Registry Number.

Microwave-assisted fluorination of 2-acylpyrroles: Synthesis of fluorohymenidin

Troegel, Benjamin,Lindel, Thomas

, p. 468 - 471 (2012)

Treatment of mono- and nonbrominated 2-acylpyrroles with Selectfluor under microwave conditions leads to fluorination of the pyrrole ring in the 5-position. In particular, 2-trichloroacetylated pyrrole can be fluorinated. As an example, dihydrofluorohymenidin was synthesized and dehydrogenated to fluorohymenidin as the first fluorinated pyrrole-imidazole alkaloid. Introduction of the vinyl double bond was achieved by chlorination of the 2-aminoimidazole moiety, followed by dehydrochlorination at 100 °C in DMF.
