Check Digit Verification of cas no

The CAS Registry Mumber 1313735-48-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,7,3 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1313735-48:
(9*1)+(8*3)+(7*1)+(6*3)+(5*7)+(4*3)+(3*5)+(2*4)+(1*8)=136
136 % 10 = 6
So 1313735-48-6 is a valid CAS Registry Number.

Metal-free C(sp3)-H bond sulfonyloxylation of 2-alkylpyridines and alkylnitrones

Wang, Chang-Sheng,Dixneuf, Pierre H.,Soulé, Jean-Fran?ois

supporting information, p. 4954 - 4957 (2018/07/25)

Pyridin-2-ylmethyl tosylate derivatives are obtained in high yields from 2-alkylpyridine 1-oxides via a [3,3]-sigmatropic rearrangement of the adduct between 2-alkylpridine 1-oxides with benzenesulfonyl chlorides. Moreover, alkylnitrones also undergo [3,3]-sigmatropic rearrangement to give α-tosylated ketones after hydrolysis. Substitution reactions with nucleophiles then lead to diverse useful functionalizations for the synthesis of pincer ligands.
