Check Digit Verification of cas no
The CAS Registry Mumber 67640-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67640-33:
(7*6)+(6*7)+(5*6)+(4*4)+(3*0)+(2*3)+(1*3)=139
139 % 10 = 9
So 67640-33-9 is a valid CAS Registry Number.

General synthetic pathway to oxygenated 3-methylbenz[g]isoquinoline- 5,10-diones

, p. 737 - 750 (2007/10/03)
The synthesis of naturally occurring dioxygenated and trioxygenated 3- methylbenz[g]isoquinoline-5,10-diones has been accomplished. The critical step involved regioselective additions of di- or trifluorobenzylzinc bromides to activated methyl 6-methylnicotinate. Aromatizations of the resultant dihydropyridines followed by hydrolysis led to the corresponding benzylpyridinecarboxylic acids which on annulative-oxidations led to the respective difluoro- or trifluorobenz[g]isoquinoline-5,10-diones. Displacements of fluorides by methoxide led to the di- or trimethoxy analogues which on selective demethylations led to bostrycoidin, 8-O- methylbostrycoidin, tolypocladin, 5-deoxybostrycoidin or 5-deoxy-6-O-methyl- bostrycoidin. The synthesis of isobostrycoidin and isotolypocladin has also been accomplished.
