Check Digit Verification of cas no

The CAS Registry Mumber 17180-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,8 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17180-57:
(7*1)+(6*7)+(5*1)+(4*8)+(3*0)+(2*5)+(1*7)=103
103 % 10 = 3
So 17180-57-3 is a valid CAS Registry Number.

Synthesis of Ketones through Microwave Irradiation Promoted Metal-Free Alkylation of Aldehydes by Activation of C(sp3)-H Bond

Zhang, Xinying,Wang, Zhangxin,Fan, Xuesen,Wang, Jianji

, p. 10660 - 10667 (2015)

In this paper, a novel methodology for the synthesis of ketones via microwave irradiation promoted direct alkylation of aldehydes by activation of the inert C(sp3)-H bond has been developed. Notably, the reactions were accomplished under metal-free conditions and used commercially available aldehydes and cycloalkanes as substrates without prefunctionalization. By using this novel method, an alternative synthetic approach toward the key intermediates for the preparation of the pharmaceutically valuable oxaspiroketone derivatives was successfully established.
