Check Digit Verification of cas no

The CAS Registry Mumber 1345700-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,7,0 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1345700-45:
(9*1)+(8*3)+(7*4)+(6*5)+(5*7)+(4*0)+(3*0)+(2*4)+(1*5)=139
139 % 10 = 9
So 1345700-45-9 is a valid CAS Registry Number.

Synthesis and alkylation of spiro-2-oxazolines containing fused 3,4-dihydropyrazin-2(1H)-ones

Music, Irena,Vercek, Bojan

experimental part, p. 2353 - 2364 (2011/11/29)

Spiro-2-oxazolines containing 3,4-dihydroquinoxalin-2(1H)-one, 3,4-dihydrobenzoquinoxalin-2(1H)-one, 1,2-dihydropyrido[2,3-b]pyrazin-3(4H)- one or 5,6-dihydropteridin-7(8H)-one moiety were prepared by heating of aromatic or heteroaromatic diamines with 2-benzoylamino-3-chloropropenoic acid in the presence of triethylamine. Treatment of spiro-2-oxazolines with MeI or EtBr using Bu4NHSO4 and K2CO3 introduced the methyl or ethyl group on the lactam nitrogen atom.
