Check Digit Verification of cas no
The CAS Registry Mumber 445373-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,3,7 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 445373-11:
(8*4)+(7*4)+(6*5)+(5*3)+(4*7)+(3*3)+(2*1)+(1*1)=145
145 % 10 = 5
So 445373-11-5 is a valid CAS Registry Number.

Ring selective lithiation of 3,5-lutidine. A new route to heterocyclic building blocks
Gros, Philippe,Viney, Cédric,Fort, Yves
, p. 628 - 630 (2007/10/03)
The first direct ring lithiation of 3,5-lutidine has been performed by the BuLi-LiDMAE reagent. Successful sequential metallations and electrophilic condensations have been performed giving access to new useful polysubstituted pyridines.
