1440076-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440076-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,0,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1440076-99:
(9*1)+(8*4)+(7*4)+(6*0)+(5*0)+(4*7)+(3*6)+(2*9)+(1*9)=142
142 % 10 = 2
So 1440076-99-2 is a valid CAS Registry Number.

Efficient synthesis of N -(9-Xanthyl)-4-toluenesulfonamides enabled by an addition-cyclization cascade of arynes
Lu, Shan-Shan,Lu, Chong-Dao
, p. 640 - 644 (2013)
An efficient synthesis of N-(9-xanthyl)-4-toluenesulfonamides is described in which salicyl N-tosylimines react with silylaryl triflates in the presence of CsF. This mild process involves an addition-cyclization cascade in which arynes are generated and t
