Check Digit Verification of cas no

The CAS Registry Mumber 137786-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,8 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137786-59:
(8*1)+(7*3)+(6*7)+(5*7)+(4*8)+(3*6)+(2*5)+(1*9)=175
175 % 10 = 5
So 137786-59-5 is a valid CAS Registry Number.

Selective halogen - Magnesium exchange reaction via organomagnesium ate complex

Inoue,Kitagawa,Shinokubo,Oshima

, p. 4333 - 4339 (2001)

Halogen-magnesium exchange of various aryl halides is achieved with a magnesium ate complex at low temperatures. Tributylmagnesate (nBu3MgLi) induces facile iodine-magnesium exchange at -78 °C. Dibutylisopropylmagnesate (iPrnBu2MgLi) is more reactive than nBu3MgLi, and this reagent accomplishes selective bromine-magnesium exchange at -78 °C. This procedure is utilized for the preparation of various polyfunctionalized arylmagnesium species. The exchange of alkenyl halides using this method proceeds with retention of configuration of the double bond.
