Check Digit Verification of cas no

The CAS Registry Mumber 1338726-56-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,7,2 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1338726-56:
(9*1)+(8*3)+(7*3)+(6*8)+(5*7)+(4*2)+(3*6)+(2*5)+(1*6)=179
179 % 10 = 9
So 1338726-56-9 is a valid CAS Registry Number.

DABCO-catalyzed [2+2] cycloaddition reactions of allenoates and trifluoromethylketones: Synthesis of 2-alkyleneoxetanes

Wang, Tong,Chen, Xiang-Yu,Ye, Song

, p. 5488 - 5490 (2011)

DABCO was found to be an efficient catalyst for the formal [2+2] cycloaddition reaction of allenoates and trifluoromethylketones (Paterno-Buchi reaction) to give the corresponding 2-alkyleneoxetanes in good yields with good diastereoselectivities.
