Check Digit Verification of cas no

The CAS Registry Mumber 1644384-68-8 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 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1644384-68:
(9*1)+(8*6)+(7*4)+(6*4)+(5*3)+(4*8)+(3*4)+(2*6)+(1*8)=188
188 % 10 = 8
So 1644384-68-8 is a valid CAS Registry Number.

Practical Continuous-Flow Trapping Metalations of Functionalized Arenes and Heteroarenes Using TMPLi in the Presence of Mg, Zn, Cu, or la Halides

Becker, Matthias R.,Knochel, Paul

supporting information, p. 12501 - 12505 (2015/10/12)

The flow metalation of various arenes and heteroarenes involving an in situ trapping with metal salts (ZnCl2. LiCl, MgCl2, CuCN. LiCl, LaCl3. LiCl) under very convenient conditions (0 ?C, 40 s) is reported. The resulting Mg, Zn, Cu, or La organic species are trapped with various electrophiles in high yields. In several cases, unusual kinetically controlled regioselectivities are obtained. All these flow metalations can be scaled up simply by extending the reaction time and without further optimization. The reaction scope of such flow metalations is considerably broader than that of the corresponding batch procedures.
