Check Digit Verification of cas no

The CAS Registry Mumber 17214-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,1 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17214-47:
(7*1)+(6*7)+(5*2)+(4*1)+(3*4)+(2*4)+(1*7)=90
90 % 10 = 0
So 17214-47-0 is a valid CAS Registry Number.

Palladium-catalyzed highly selective intramolecular bromoamination of alkenes: Efficient synthesis of substituted pyrrolidines

Zhang, Jingfang,Wang, Xie,Liu, Yulong,Wang, Xiaoyun,He, Wei

, (2017/05/22)

A new method has been developed for the preparation of substituted pyrrolidines by the palladium-catalyzed intramolecular bromoamination of substituted aminoalkenes. The catalytic system and reaction conditions used for this transformation have been fully optimized. Notably, this reaction exhibits excellent selectivity, affording the pyrrolidine products as single 5-exo-bromoalkylpyrrolidines in excellent yields. Furthermore, this reaction occurs at room temperature under mild conditions, reaching completion within 1?h.
