Check Digit Verification of cas no

The CAS Registry Mumber 18741-86-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,4 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18741-86:
(7*1)+(6*8)+(5*7)+(4*4)+(3*1)+(2*8)+(1*6)=131
131 % 10 = 1
So 18741-86-1 is a valid CAS Registry Number.

Stabilized well-dispersed Pd(0) nanoparticles for aminocarbonylation of aryl halides

Zhu, Yinghuai,Chuanzhao, Li,Biying, Algin Oh,Sudarmadji, Meriska,Chen, Anqi,Tuan, Dang Thanh,Seayad, Abdul M

, p. 9320 - 9325 (2011)

Well-dispersed palladium (0) nanoparticles stabilized with phosphonium based ionic liquid were synthesized conveniently and fully characterized. A catalyst system comprising of the Pd(0) nanoparticles and a base was found to be recyclable and efficient for the aminocarbonylation reaction of aryl iodide in ionic liquid media. In the presence of potassium tert-butyloxide, for the relatively stable aryl chloride and bromide substrates, medium activities were achieved for the catalyst. The catalyst composites can be recycled at least five times with sustained activity.
