Check Digit Verification of cas no

The CAS Registry Mumber 21239-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21239-75:
(7*2)+(6*1)+(5*2)+(4*3)+(3*9)+(2*7)+(1*5)=88
88 % 10 = 8
So 21239-75-8 is a valid CAS Registry Number.

N-Fluorobenzenaminium tetrafluoroborate generated in situ by aniline and Selectfluor as a reusable catalyst for the ring opening of epoxides with amines under microwave irradiation

Chauhan, Manmohan Singh,Yadav, Geeta Devi,Hussain, Firasat,Singh, Surendra

, p. 3945 - 3952 (2014)

The ring opening of epoxides with aromatic and aliphatic amines was carried out under solvent free conditions using N-fluorobenzenaminium tetrafluoroborate (2 mol%) generated in situ by the reaction of aniline and Selectfluor as a catalyst with microwave irradiation. Excellent yields of β-amino alcohols were obtained. The catalyst also results in the retention of the stereochemistry for the ring opening of enantiopure epoxide with amine. The catalyst was recovered and reused up to 4 cycles for the ring opening of cyclohexene oxide with aniline. This journal is

Glycerine and CeClH: An efficient and recyclable reaction medium for ring opening of epoxides with thioamides and amines

Narsaiah, A. Venkat,Wadavrao, Sachin B.,Reddy, A. Ramesh,Yadav

experimental part, p. 485 - 489 (2011/04/16)

Oxiranes undergo rapid ring-opening reaction with a range of thioamides and amines to afford the corresponding -amino alcohol derivatives. The reactions were carried out using glycerine and cerium(III) chloride as a recyclable reaction medium. All the reactions were carried out at room temperature and the products were obtained in excellent yields. Georg Thieme Verlag Stuttgart New York.
