Check Digit Verification of cas no

The CAS Registry Mumber 1253075-41-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,0,7 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1253075-41:
(9*1)+(8*2)+(7*5)+(6*3)+(5*0)+(4*7)+(3*5)+(2*4)+(1*1)=130
130 % 10 = 0
So 1253075-41-0 is a valid CAS Registry Number.

An efficient three-component domino synthesis of difluoromethyl-containing 1,4-dihydropyridines under solvent and catalyst free conditions

Li, Hui,Yu, Jinlong,Cao, Song,Shen, Li,Wu, Mingxi,Cheng, Jianhang,Qian, Xuhong

experimental part, p. 1509 - 1513 (2010/11/03)

The difluoromethyl-containing Hantzsch 1,4-dihydropyridines were synthesized in good yields by a one-pot cyclocondensation of ethyl difluoroacetoacetate (EDFAA), a variety of aromatic aldehydes and ammonium acetate under solvent and catalyst free conditions. The comparison of reaction conditions and products was made among the different 1,3-carbonyl substrates (ethyl acetoacetate, ethyl difluoroacetoacetate and ethyl trifluoroacetoacetate) for the Hantzsch reaction.
