Check Digit Verification of cas no

The CAS Registry Mumber 1220015-97-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,0,1 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1220015-97:
(9*1)+(8*2)+(7*2)+(6*0)+(5*0)+(4*1)+(3*5)+(2*9)+(1*7)=83
83 % 10 = 3
So 1220015-97-3 is a valid CAS Registry Number.

Exceptionally mild palladium(II)-catalyzed dehydrogenative C-H/C-H arylation of indolines at the C-7 position under air

Jiao, Lin-Yu,Smirnov, Polina,Oestreich, Martin

, p. 6020 - 6023 (2014)

An improved method for the dehydrogenative C-H/C-H cross-coupling at the C-7 position of indolines containing a urea as a directing group is reported. The new protocol is a rare example of an aerobic palladium(II)-catalyzed cross dehydrogenative coupling (CDC) reaction that proceeds at low temperature. The use of either Cu(OAc)2 in an open flask or dioxygen (balloon) at 50 °C tolerates indolines not substituted at C-2 and C-3, thereby extending the scope of the previous method that suffers from indoline-to-indole oxidation.

Direct synthesis of 8-aryl tetrahydroquinolines via pd-catalyzed ortho-arylation of aryl ureas in water

Jiang, Zhen,Zhang, Lingjuan,Dong, Chaonan,Su, Xiaoming,Li, Huanrong,Tang, Weijun,Xu, Lijin,Fan, Qinghua

, p. 1025 - 1028 (2013/03/13)

An efficient protocol for the direct synthesis of 8-arylated tetrahydroquinolines via Pd-catalyzed ortho-arylation of aryl ureas with aryl iodides was developed. The reaction proceeded smoothly in water under ligand-free and surfactant-free conditions, pr
