Check Digit Verification of cas no

The CAS Registry Mumber 1444335-43-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,4,3,3 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1444335-43:
(9*1)+(8*4)+(7*4)+(6*4)+(5*3)+(4*3)+(3*5)+(2*4)+(1*3)=146
146 % 10 = 6
So 1444335-43-6 is a valid CAS Registry Number.

6-Amino-2,4,5-trimethylpyridin-3-ols: A new general synthetic route and antiangiogenic activity

Kim, Dong-Guk,Kang, Youra,Lee, Hyunji,Lee, Eun Kyung,Nam, Tae-Gyu,Kim, Jung-Ae,Jeong, Byeong-Seon

, p. 126 - 139 (2014/04/17)

A new synthetic strategy for preparation of a wide range of 6-amino-2,4,5-trimethylpyridin-3-ols from pyridoxine·HCl via a six-step sequence has been developed. This approach features an introduction of various amino groups to C(6)-position of 3-benzyloxy-6-bromo-2,4,5-trimethylpyridine (13), a key intermediate, by a Buchwald-Hartwig amination reaction using palladium(0) transition metal, which certainly renders an expanded scope of amino substituents. Some analogs prepared using the methods described here showed high level of antiangiogenic and antitumor activities in chick chorioallantoic membrane (CAM) assay, demonstrating the potential of these new aminopyridinols as antiangiogenic agents.
