Check Digit Verification of cas no

The CAS Registry Mumber 1334333-29-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,3,3 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334333-29:
(9*1)+(8*3)+(7*3)+(6*4)+(5*3)+(4*3)+(3*3)+(2*2)+(1*9)=127
127 % 10 = 7
So 1334333-29-7 is a valid CAS Registry Number.

Direct C(sp3)–H allylation of 2-alkylpyridines with Morita–Baylis–Hillman carbonates via a tandem nucleophilic substitution/aza-Cope rearrangement

Ning, Shulin,Wang, Shutao,Wang, Siyu,Xiang, Jinbao,Zhang, Zhuoqi,Zheng, Lianyou

supporting information, p. 2505 - 2510 (2021/10/16)

A base- and catalyst-free C(sp3)–H allylic alkylation of 2-alkylpyridines with Morita–Baylis–Hillman (MBH) carbonates is described. A plausible mechanism of the reaction might involve a tandem SN2’ type nucleophilic substitution followed by an aza-Cope rearrangement. Various alkyl substituents on 2-alkylpyridines were tolerated in the reaction to give the allylation products in 26–91% yields. The developed method provides a straightforward and operational simple strategy for the allylic functionalization of 2-alkypyridine derivatives.
