Check Digit Verification of cas no

The CAS Registry Mumber 1419174-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,9,1,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1419174-52:
(9*1)+(8*4)+(7*1)+(6*9)+(5*1)+(4*7)+(3*4)+(2*5)+(1*2)=159
159 % 10 = 9
So 1419174-52-9 is a valid CAS Registry Number.

Direct lactonization of 2-arylacetic acids through Pd(II)-catalyzed C-H activation/C-O formation

Yang, Mingyu,Jiang, Xingyu,Shi, Wen-Juan,Zhu, Qi-Lei,Shi, Zhang-Jie

, p. 690 - 693 (2013/04/10)

Palladium-catalyzed direct lactonization of 2-arylacetic acids through a reaction sequence that includes C-H activation/C-O formation is reported. This method provides a concise and efficient pathway to synthesize fully functionalized benzofuranone derivatives, which are highly relevant to bioactive natural and synthetic products.
