Check Digit Verification of cas no

The CAS Registry Mumber 929880-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,8,8 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 929880-43:
(8*9)+(7*2)+(6*9)+(5*8)+(4*8)+(3*0)+(2*4)+(1*3)=223
223 % 10 = 3
So 929880-43-3 is a valid CAS Registry Number.

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.
