Check Digit Verification of cas no
The CAS Registry Mumber 30235-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,2,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 30235-20:
(7*3)+(6*0)+(5*2)+(4*3)+(3*5)+(2*2)+(1*0)=62
62 % 10 = 2
So 30235-20-2 is a valid CAS Registry Number.

Application of organolithium and related reagents in synthesis. Part 9. Synthesis and metallation of 4-chloropicolin- and 2-chloroisonicotinanilides. A useful method for preparation of 2,3,4-trisubstituted pyridines

The synthesis and metallation (nBuLi) of 4-chloropicolin- and 2-chloroisonicotinanilides (1) and (2) as a way of regiospecific transformation of picolinic and isonicotinic acids into 2,3,4-trisubstituted pyridines (9) and (10), is described. The anilide moiety (masking group) of the formed C3-substituted chloro-anilides (9) and (10) appeared to be effectively removable on acid hydrolysis.
