Check Digit Verification of cas no

The CAS Registry Mumber 135329-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,2 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135329-03:
(8*1)+(7*3)+(6*5)+(5*3)+(4*2)+(3*9)+(2*0)+(1*3)=112
112 % 10 = 2
So 135329-03-2 is a valid CAS Registry Number.

A convenient synthesis of 2-alkylthio-4,5-dihydro-5-methoxythiazoles

Lee,Jeong,Choi,Kim,Park

, p. 494 - 496 (1991)

A series of 2-alkylthio-4,5-dihydro-5-methoxythiazoles 3 were prepared by thermal or diethyl ether-boron trifluoride mediated intramolecular cyclization of the corresponding N-(2,2-dimethoxyethyl)dithiocarbamic acid esters 2. Methyl N-(2,2-dimethoxyethyl)dithiocarbamate (36) and 4,5-dihydro-5-methoxy-2-methylthiothiazole (3b) were converted by a two-step sequence to methyl 2-methyl-3-thioxo-1,2,3,4-tetrahydro-1,2,4-triazine-4-carbodithioate (6).
