1140788-24-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1140788-24-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,7,8 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1140788-24:
(9*1)+(8*1)+(7*4)+(6*0)+(5*7)+(4*8)+(3*8)+(2*2)+(1*4)=144
144 % 10 = 4
So 1140788-24-4 is a valid CAS Registry Number.

A significant substituent effect on the regioselectivity in addition of alkynes to 3-substituted pyridines

Yamada, Shinji,Toshimitsu, Aya,Takahashi, Yasuko

experimental part, p. 2329 - 2333 (2009/07/11)

A substituent at the 3-position on a pyridine ring significantly affects the regioselectivity during the addition of alkynes to pyridinium salts. When the substituent is an electron-withdrawing group, 1,6-adducts are predominantly produced, whereas, 1,2-a
