Check Digit Verification of cas no

The CAS Registry Mumber 102336-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,3 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102336-05:
(8*1)+(7*0)+(6*2)+(5*3)+(4*3)+(3*6)+(2*0)+(1*5)=70
70 % 10 = 0
So 102336-05-0 is a valid CAS Registry Number.

Synthesis of 2-Substituted 4-Pyridylpropionates. Part 2. Alkylation Approach

Adger, Brian M.,Ayrey, Peter,Bannister, Robin,Forth, Michael A.,Hajikarimian, Yousef,et al.

, p. 2791 - 2796 (2007/10/02)

A synthesis of methyl 3-(2-methoxy-4-pyridyl)propionate (2), a key intermediate in the synthesis of the potent long-acting histamine H2-receptor antagonist SK&F 93574 (1), is described.The key step in the synthesis of compound (1) involves alkylation of 2-methoxy-4-methylpyridine (5) with sodium chloroacetate in the presence of sodamide.The scope and limitations of the alkylation is investigated using a variety of electrophiles.The application of this reaction to other 2-substituted 4-methylpyridines is also discussed.
