1057732-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1057732-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,7,3 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1057732-45:
(9*1)+(8*0)+(7*5)+(6*7)+(5*7)+(4*3)+(3*2)+(2*4)+(1*5)=152
152 % 10 = 2
So 1057732-45-2 is a valid CAS Registry Number.

Selective generation of lithiated benzonitriles: The importance of reaction conditions
Lulinski, Sergiusz,Zajac, Katarzyna
, p. 7785 - 7788 (2008/12/22)
(Chemical Equation Presented) Lithiated benzonitriles can be generated in high yields from reactions of bromobenzonitriles with n-BuLi in THF under standard cryogenic conditions (ca. -70°C) provided the reverse addition mode is employed. The resultant ary
