Check Digit Verification of cas no

The CAS Registry Mumber 1408236-64-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,8,2,3 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1408236-64:
(9*1)+(8*4)+(7*0)+(6*8)+(5*2)+(4*3)+(3*6)+(2*6)+(1*4)=145
145 % 10 = 5
So 1408236-64-5 is a valid CAS Registry Number.

Efficient synthesis of trifluoromethylated dihydrochalcones, aryl vinyl ketones and indanones by superelectrophilic activation of 4,4,4-trifluoro/3- (trifluoromethyl)crotonic acids

, p. 292 - 302 (2013/01/13)

Superacid catalyzed electrophilic substitution of arenes using 4,4,4,-trifluoro/3-trifluoromethylcrotonic acids has been investigated. The direct synthesis of various trifluoromethylated dihydrochalcones, aryl vinyl ketones and indanones has been achieved by this methodology. It has been found that the position of the trifluoromethyl group has a profound effect on the nature of the reaction and the products. In the pharmaceutical industry, many fluoroorganics are shown to possess significant biological and therapeutic activities. Therefore, these novel compounds can be considered key intermediates for the preparation of potential biologically active molecules.
