1011736-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1011736-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,1,7,3 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1011736-21:
(9*1)+(8*0)+(7*1)+(6*1)+(5*7)+(4*3)+(3*6)+(2*2)+(1*1)=92
92 % 10 = 2
So 1011736-21-2 is a valid CAS Registry Number.

Ag+-mediated synthesis of substituted furo[2,3-b]pyrazines
Ermolat'ev, Denis S.,Mehta, Vaibhav Pravinchandra,Van Der Eycken, Erik V.
, p. 3117 - 3122 (2008/09/19)
A highly efficient method for the preparation of trisubstituted furo[2,3-b]pyrazines has been developed. Sonogashira coupling reaction with the readily available 1-(4-methoxybenzyl)-3,5-dichloropyrazin-2(1H)-ones was followed by silver-catalyzed heteroann
