Check Digit Verification of cas no

The CAS Registry Mumber 1228296-10-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,9 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228296-10:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*9)+(3*6)+(2*1)+(1*0)=153
153 % 10 = 3
So 1228296-10-3 is a valid CAS Registry Number.

Unusual carbon-carbon bond formations between allylboronates and acetals or ketals catalyzed by a peculiar indium(I) lewis acid

Schneider, Uwe,Dao, Hai T.,Kobayashi, Shu

supporting information; experimental part, p. 2488 - 2491 (2010/07/05)

InIOTf has been uncovered as an effective Lewis acid catalyst for unprecedented nucleophilic substitution of acetals or ketals with allylboronates. A transmetalative SN1 mechanism is proposed in which a single InI center acts as a dual catalyst to activate both reagents sequentially. Contrary to the classic γ-selectivity of allylsilanes (Hosomi-Sakurai reaction), this InI-catalyzed borono variant displays distinct α-selectivity. Substrate scope and functional group tolerance proved to be excellent.
