1512844-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1512844-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,2,8,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1512844-40:
(9*1)+(8*5)+(7*1)+(6*2)+(5*8)+(4*4)+(3*4)+(2*4)+(1*0)=144
144 % 10 = 4
So 1512844-40-4 is a valid CAS Registry Number.

Synthesis of sulfur-bridged polycycles via Pd-catalyzed dehydrogenative cyclization

Wang, Binjie,Liu, Yue,Lin, Cong,Xu, Yiming,Liu, Zhanxiang,Zhang, Yuhong

, p. 4574 - 4577 (2015/01/08)

A general approach to sulfur-bridged polycycles by palladium-catalyzed double C(sp2)-H bond oxidative cyclization is presented. This protocol afforded diverse sulfur-bridged five-, six-, and seven-membered polycycles in moderate to good yields with a tolerance for a wide variety of functional groups. A sulfide-bridged six-membered pyrene-thienoacene compound was synthesized readily using this method, and excellent performance for photoluminescence quantum yield was observed.
