Check Digit Verification of cas no

The CAS Registry Mumber 1644382-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,3,8 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1644382-37:
(9*1)+(8*6)+(7*4)+(6*4)+(5*3)+(4*8)+(3*2)+(2*3)+(1*7)=175
175 % 10 = 5
So 1644382-37-5 is a valid CAS Registry Number.

Palladium(II)-catalyzed intramolecular tandem aminoalkylation via divergent C(sp3)-H functionalization

Du, Wei,Gu, Qiangshuai,Li, Zhongliang,Yang, Dan

supporting information, p. 1130 - 1135 (2015/02/05)

(Chemical Equation Presented) We have developed a Pd(II)-catalyzed oxidative tandem aminoalkylation via divergent C(sp3)-H functionalization, a ffording three- and five-membered-ring fused indolines in good yields under two optimized conditions, respectively. The mechanism studies have indicated that the benzylic C - H cleavage involved in the former transformation is the rate-determining step, while the cleavage of amide α-C - H in the latter is not. This is the first example of a Pd-catalyzed tandem reaction involving C(sp3)-H activation without the employment of prefunctionalized reagents (e.g., halogenated and boron reagents) and directing groups, representing a green and economic protocol for the construction of N-containing heterocycles.
