Check Digit Verification of cas no
The CAS Registry Mumber 226717-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,7,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 226717-83:
(8*2)+(7*2)+(6*6)+(5*7)+(4*1)+(3*7)+(2*8)+(1*3)=145
145 % 10 = 5
So 226717-83-5 is a valid CAS Registry Number.

General synthetic pathway to oxygenated 3-methylbenz[g]isoquinoline- 5,10-diones
Krapcho, A. Paul,Waterhouse, David J.
, 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.
