Check Digit Verification of cas no

The CAS Registry Mumber 1370422-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,4,2 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1370422-90:
(9*1)+(8*3)+(7*7)+(6*0)+(5*4)+(4*2)+(3*2)+(2*9)+(1*0)=134
134 % 10 = 4
So 1370422-90-4 is a valid CAS Registry Number.

Palladium-catalyzed direct C-H bond alkynylations of heteroarenes using gem-dichloroalkenes

Ackermann, Lutz,Kornhaass, Christoph,Zhu, Yingjun

supporting information; experimental part, p. 1824 - 1826 (2012/06/29)

Palladium-catalyzed direct alkynylations of heteroarenes were accomplished with inexpensive gem-dichloroalkenes as user-friendly electrophiles, which set the stage for a modular, step-economical synthesis of diversely decorated heteroaryl alkynes with amp
