Check Digit Verification of cas no

The CAS Registry Mumber 129729-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,2 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129729-66:
(8*1)+(7*2)+(6*9)+(5*7)+(4*2)+(3*9)+(2*6)+(1*6)=164
164 % 10 = 4
So 129729-66-4 is a valid CAS Registry Number.

The influence of substituents in 3-position on the activity of chroman-type potassium channel activators

Bergmann,Gericke

, p. 169 - 173 (2007/10/02)

Swern oxidation of chromanol 1 led to ketone 3 with concomitant chlorination of the adjacent 4-position. Using Leuckart conditions, chromanone 2 was converted to enamine 5. - 4-Bromochromene-3-carbaldehyde 8, which was obtained by Vilsmeier-Arnold reaction from 7, turned out to be a suitable intermediate for the insertion of the pyridone residue. 3-Chloro derivatives 16 and 19 resulted on heating the mesylate or tosylate with LiC1 in DMF. Bromination of chromene 20 led to 21. - All compounds were tested for oral antihypertensive activity in spontaneously hypertensive rats with a dose of 1 mg/kg.
