Check Digit Verification of cas no

The CAS Registry Mumber 1334163-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,6 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1334163-75:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*6)+(3*3)+(2*7)+(1*5)=135
135 % 10 = 5
So 1334163-75-5 is a valid CAS Registry Number.

Generation of diverse 2-pyrones via palladium-catalyzed site-selective Suzuki-Miyaura couplings of 3-bromo-4-tosyloxy-2-pyrone

Lei, Xiaoli,Gao, Liang,Ding, Qiuping,Peng, Yiyuan,Wu, Jie

supporting information; experimental part, p. 6265 - 6270 (2011/10/09)

Based on different reactivity of the (pseudo)halide substituents in the 2-pyrone (3-Br and 4-OTs), palladium-catalyzed sequential site-selective Suzuki-Miyaura cross-coupling reactions of 3-bromo-6-methyl-4-tosyloxy-2-pyrone are described, which afford the diverse 2-pyrones in good yields.
