Check Digit Verification of cas no

The CAS Registry Mumber 1396604-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,6,6,0 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1396604-89:
(9*1)+(8*3)+(7*9)+(6*6)+(5*6)+(4*0)+(3*4)+(2*8)+(1*9)=199
199 % 10 = 9
So 1396604-89-9 is a valid CAS Registry Number.

Palladium-Catalyzed Carbonylative Annulation Reactions Using Aryl Formate as a CO Source: Synthesis of 2-Substituted Indene-1,3(2H)-dione Derivatives

Zhang, Ying,Chen, Jing-Lei,Chen, Zhen-Bang,Zhu, Yong-Ming,Ji, Shun-Jun

, p. 10643 - 10650 (2015)

An efficient synthesis of 2-substituted indene-1,3(2H)-diones from stable and readily available 1-(2-halophenyl)-1,3-diones by employing phenyl formate as a CO source has been developed. The reaction occurred via palladium-catalyzed intramolecular carbonylative annulation using K3PO4 as a base and DMSO as a solvent at 95 °C. In this protocol, the reaction showed a broad substrate scope with good to excellent yields.
