Check Digit Verification of cas no

The CAS Registry Mumber 1239984-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,8 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1239984-63:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*8)+(3*4)+(2*6)+(1*3)=204
204 % 10 = 4
So 1239984-63-4 is a valid CAS Registry Number.

A new method for the synthesis of 3-aryl-6-(2-pyrrolyl)pyridazines

Song, Chuanjun,Zhao, Peng,Liu, Yan,Liu, Hui,Li, Wenjia,Shi, Shuai,Chang, Junbiao

experimental part, p. 5378 - 5383 (2010/08/06)

A new method for the synthesis of 3-halo-6-(N-tosyl-2-pyrrolyl)pyridazine 7 was developed.Suzuki cross-coupling reactions of 7 with arylboronic acids and in situ de-tosylation gave a variety of novel 3-aryl-6-(2-pyrrolyl)pyridazines. It found that protection of the pyrrolyl moiety was necessary for efficient coupling reaction.
