Check Digit Verification of cas no

The CAS Registry Mumber 1418035-93-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,8,0,3 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1418035-93:
(9*1)+(8*4)+(7*1)+(6*8)+(5*0)+(4*3)+(3*5)+(2*9)+(1*3)=144
144 % 10 = 4
So 1418035-93-4 is a valid CAS Registry Number.

Assembly of fused indenes via Au(i)-catalyzed C1-C5 cyclization of enediynes bearing an internal nucleophile

Hou, Qiwen,Zhang, Zhenhua,Kong, Fanji,Wang, Shaozhong,Wang, Huaqin,Yao, Zhu-Jun

supporting information, p. 695 - 697 (2013/02/25)

A tandem reaction initiated by Au(i)-catalyzed C1-C5 cyclization of enediynes bearing an internal carboxy nucleophile has been developed, providing a distinctive methodology for the assembly of fused indenes including indeno[1,2-c]isochromen-5(11H)-ones and indeno[1,2-b]pyran-2(5H)-ones. A mechanism involving the concerted formation of the five- and six-membered rings was proposed.
