Check Digit Verification of cas no

The CAS Registry Mumber 74976-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,7 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74976-77:
(7*7)+(6*4)+(5*9)+(4*7)+(3*6)+(2*7)+(1*7)=185
185 % 10 = 5
So 74976-77-5 is a valid CAS Registry Number.

Palladium-catalyzed allylic alkylation of carbonucleophiles with allylic borates or allylic alcohols and boron oxide under neutral conditions

Lu, Xiyan,Jiang, Xiaohui,Tao, Xiaochun

, p. 109 - 118 (2007/10/02)

Under neutral conditions, Pd(PPh3)4 catalyzes the allylic alkylation of carbonucleophiles with allylic borates in high yields.Moreover, allylic borates are formed in situ from allylic alcohols with boron oxide, and the Pd-catalyzed allylic alkylation was achieved simply by the reaction of allylic alcohols with a nucleophile in the presesnce of boron oxide by a one-pot procedure.The mechanisms of these reactions are discussed.
