1287784-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1287784-28-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,7,8 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1287784-28:
(9*1)+(8*2)+(7*8)+(6*7)+(5*7)+(4*8)+(3*4)+(2*2)+(1*8)=214
214 % 10 = 4
So 1287784-28-4 is a valid CAS Registry Number.

Synthesis of electron-rich thiamacrocycles
Holy, Petr,Buchta, Michal,Rybacek, Jiri,Hodaocova, Jana,Cisarova, Ivana
experimental part, p. 4169 - 4176 (2011/02/22)
The stepwise syntheses of large [4+4] electron-rich thiamacrocycles, which aim at fullerene complexation, were performed using two types of building blocks, viz. 1,4-bis(bromomethyl)benzene or its dibutoxylated analogue and 4,5-bis(2-cyanoethyl-sulfanyl)-
