Check Digit Verification of cas no

The CAS Registry Mumber 1253969-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,9,6 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253969-55:
(9*1)+(8*2)+(7*5)+(6*3)+(5*9)+(4*6)+(3*9)+(2*5)+(1*5)=189
189 % 10 = 9
So 1253969-55-9 is a valid CAS Registry Number.

Synthesis and Quantum Chemical Studies of New 4-aminoquinazoline Derivatives as Aurora A/B Kinase Inhibitors

Zheng, Ming,Zheng, Youguang,Xue, Yunsheng,Liu, Yi,An, Lin,Zhang, Ling,Ji, Min,Xue, Bai,Wu, Xuan,Gong, Xuedong,Gu, Ning,Zhan, Xi

, p. 399 - 407 (2013)

Nine novel 4-aminoquinazoline derivatives were designed and synthesized. Biochemical and cellular analyses demonstrated that most of the derivatives exhibited a strong activity to inhibit Aurora A and B kinases and to suppress the proliferation of a panel of human tumor cell lines (U937, K562, A549, LoVo, and HT29). Quantum chemical studies were also carried out to determine the structural features of these compounds engaged in the inhibition of Aurora kinases.
