Check Digit Verification of cas no

The CAS Registry Mumber 83419-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,1 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83419-12:
(7*8)+(6*3)+(5*4)+(4*1)+(3*9)+(2*1)+(1*2)=129
129 % 10 = 9
So 83419-12-9 is a valid CAS Registry Number.

Palladium catalyzed ring opening of furans as a route to α,β-unsaturated aldehydes

El Kaim, Laurent,Grimaud, Laurence,Wagschal, Simon

, p. 1887 - 1889 (2011/03/23)

Furans may be ring opened via pallado-catalyzed reactions leading to α,β-unsaturated aldehydes and ketones tethered to indole and isoquinoline moieties. Besides their synthetic interest, these fragmentations bring interesting elements into the discussion

Synthesis of novel 5,6-substituted furo[2,3-d]pyrimidines via Pd-catalyzed cyclization of alkynylpyrimidinols with aryl iodides

Liu, Zhende,Li, Dewen,Li, Shukun,Bai, Donglu,He, Xuchang,Hu, Youhong

, p. 1931 - 1936 (2007/10/03)

A flexible method for the synthesis of 5,6-disubstituted furo[2,3-d]pyrimidine derivatives is described. The key step is a palladium-catalyzed arylative cyclization of alkynylpyrimidinols with various aryl iodides, which gave the title compounds in 36-75% yield.
