140887-32-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140887-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,8 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140887-32:
(8*1)+(7*4)+(6*0)+(5*8)+(4*8)+(3*7)+(2*3)+(1*2)=137
137 % 10 = 7
So 140887-32-7 is a valid CAS Registry Number.

Removable groups for activation of indole photochemistry
Weedon,Zhang
, p. 95 - 100 (2007/10/02)
The ability of a series of nitrogen-substituents to activate the cycloaddition photochemistry of indoles has been examined; the N-substitutents were chosen in order to enable their removal following cycloaddition under mild neutral, acidic or basic condit
