Check Digit Verification of cas no

The CAS Registry Mumber 1448295-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,2,9 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1448295-33:
(9*1)+(8*4)+(7*4)+(6*8)+(5*2)+(4*9)+(3*5)+(2*3)+(1*3)=187
187 % 10 = 7
So 1448295-33-7 is a valid CAS Registry Number.

Ligand-dependent site-selective suzuki cross-coupling of 3,5-dichloropyridazines

Dai, Xing,Chen, Yonggang,Garrell, Stephanie,Liu, Hong,Zhang, Li-Kang,Palani, Anandan,Hughes, Gregory,Nargund, Ravi

, p. 7758 - 7763 (2013/09/02)

General methods for the highly site-selective Suzuki monocoupling of 3,5-dichloropyridazines have been discovered. By changing the ligand employed, the preferred coupling site can be switched from the 3-position to the 5-position, typically considered the less reactive C-X bond. These conditions are applicable to the coupling of a wide variety of aryl-, heteroaryl-, and vinylboronic acids with high selectivities, thus enabling the rapid construction of diverse arrays of diarylpyradazines in a modular fashion.
