Check Digit Verification of cas no

The CAS Registry Mumber 40560-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,6 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40560-92:
(7*4)+(6*0)+(5*5)+(4*6)+(3*0)+(2*9)+(1*2)=97
97 % 10 = 7
So 40560-92-7 is a valid CAS Registry Number.

LiCl-mediated preparation of highly functionalized benzylic zinc chlorides

Metzger, Albrecht,Schade, Matthias A.,Knochel, Paul

supporting information; experimental part, p. 1107 - 1110 (2009/04/06)

In the presence of zinc dust (1.5-2.0 equiv) and LiCI(1.5-2.0 equiv), various benzylic chlorides bearing functional groups (iodide, cyanide, ester, ketone) are smoothly converted at 25°C to the corresponding zinc reagents without homo-coupling (≤5%). The utility of these benzylic zinc reagents is demonstrated by a short synthesis of papaverine.
