1318261-79-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1318261-79-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,2,6 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1318261-79:
(9*1)+(8*3)+(7*1)+(6*8)+(5*2)+(4*6)+(3*1)+(2*7)+(1*9)=148
148 % 10 = 8
So 1318261-79-8 is a valid CAS Registry Number.

Modular synthesis of naphthothiophenes by Pd-catalyzed tandem direct arylation/Suzuki coupling
Nicolaus, Norman,Franke, Patrick T.,Lautens, Mark
, p. 4236 - 4239 (2011/10/11)
A short and highly modular three-step synthesis of a new class of substituted naphthothiophenes has been developed exploiting a Pd-catalyzed tandem direct arylation/Suzuki coupling transformation as the key step.
