Check Digit Verification of cas no

The CAS Registry Mumber 60975-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,9,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 60975-89:
(7*6)+(6*0)+(5*9)+(4*7)+(3*5)+(2*8)+(1*9)=155
155 % 10 = 5
So 60975-89-5 is a valid CAS Registry Number.

Applications of Organolithium and Related Reagents in Synthesis. Part 3. A General Study of the Reaction of Lithium Alkyls with Pyridine Ketones

Epsztajn, Jan,Bieniek, Adam

, p. 213 - 220 (2007/10/02)

The reaction of MeLi and PhLi with acetylpyridines (1a-c) and their annelated derivatives (2a), (2b), (3), and (4) has been examined.The 3- and 4-pyridyl ketones (1b), (1c), (3), and (4) gave similar results to acetophenone and 3,4-dihydronaphthalen-1(2H)-one.In the case of the 2-pyridyl ketones (1a), (2a), and (2b) unexpectedly low yields of products resulted from the addition of RLi to the carbonyl group; the reaction was efficiently enhanced by initially adding an additional amount of LiBr.These results were accounted for by the chelation of RLi or LiBr by the 2-pyridyl ketones.
