Check Digit Verification of cas no

The CAS Registry Mumber 847021-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,0,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 847021-17:
(8*8)+(7*4)+(6*7)+(5*0)+(4*2)+(3*1)+(2*1)+(1*7)=154
154 % 10 = 4
So 847021-17-4 is a valid CAS Registry Number.

Synthesis and biological evaluation of 7-N-(n-alkoxyphthalimido)-2hydroxy- 4-aryl-6-aryliminothiazolidino [2,3-b] pyrimidines and related compounds

Singh, Bhawani Singh,Mehta, Deepika,Baregama, Lalit K.,Talesara

, p. 1306 - 1313 (2007/10/03)

Substituted aryl thioureas 1a-c react with chloroacetic acid in the presence of anhydrous sodium acetate to furnish 2-aryliminothiazolidin-4-ones 2a-c. Condensation of ω-bromoalkoxyphthalimides 3a-c with 2a-c give the corresponding alkoxyphthalimide derivatives of 2-aryliminothiazolidin-4-ones 4a-i. These on condensation with araldehydes 5a-c yield 3-N-(alkoxyphthalimido)- 5-arylidene-2-aryliminothiazolidin-4-ones 7a-a′. In an alternative route 5a-c react with 2a-c to give 6a-i, which could be cyclised with urea in the presence of sodium acetate to yield the corresponding thiazolidinopyrimidine 8a-i. 7a-a′ are also prepared from 6a-i with 3a-c, which give final compound 9a-a′ on cyclisation. Alternatively, 8a-i when condensed with 3a-c also furnish the compounds 9a-a′. Evaluation of antimalarial and antibacterial activity is also reported.
