Check Digit Verification of cas no

The CAS Registry Mumber 1638679-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,6,7 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1638679-20:
(9*1)+(8*6)+(7*3)+(6*8)+(5*6)+(4*7)+(3*9)+(2*2)+(1*0)=215
215 % 10 = 5
So 1638679-20-5 is a valid CAS Registry Number.

Palladium-catalyzed allylic alkylation of simple ketones with allylic alcohols and its mechanistic study

Huo, Xiaohong,Yang, Guoqiang,Liu, Delong,Liu, Yangang,Gridnev, Ilya D.,Zhang, Wanbin

supporting information, p. 6776 - 6780 (2014/07/08)

Allylic alcohols were directly used in Pd-catalyzed allylic alkylations of simple ketones under mild reaction conditions. The reaction proceeded smoothly at 20°C by the concerted action of a Pd catalyst, a pyrrolidine co-catalyst, and a hydrogen-bonding solvent, and does not require any additional reagents. A computational study suggested that methanol plays a crucial role in the formation of the π-allylpalladium complex by lowering the activation barrier.
