4381-37-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4381-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4381-37:
(6*4)+(5*3)+(4*8)+(3*1)+(2*3)+(1*7)=87
87 % 10 = 7
So 4381-37-7 is a valid CAS Registry Number.

De novo synthesis of 1,4-dihydropyridines and pyridines

Gati, Wafa,Rammah, Mohamed M.,Rammah, Mohamed B.,Couty, Francois,Evano, Gwilherm

supporting information; experimental part, p. 9078 - 9081 (2012/07/13)

An efficient and general method for the synthesis of 1,4-dihydropyridines and pyridines based on a lithiation/isomerization/intramolecular carbolithiation sequence is reported. This procedure provides an efficient, divergent, and straightforward entry to a wide range of polysubstituted dihydropyridines and pyridines starting from readily available N-allyl-ynamides.
