862972-59-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 862972-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,9,7 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 862972-59:
(8*8)+(7*6)+(6*2)+(5*9)+(4*7)+(3*2)+(2*5)+(1*9)=216
216 % 10 = 6
So 862972-59-6 is a valid CAS Registry Number.

Bifunctional asymmetric catalysis with hydrogen chloride: Enantioselective ring opening of aziridines catalyzed by a phosphinothiourea

Mita, Tsuyoshi,Jacobsen, Eric N.

, p. 1680 - 1684 (2009)

Ring opening of aziridines with hydrogen chloride to form β-chloroamine derivatives is catalyzed by a chiral phosphinothiourea derivative in high yields and with high enantioselectivities. On the basis of 31P NMR studies, activation of HCl appears to proceed via quantitative protonation of the catalyst to afford a phosphonium chloride complex. Georg Thieme Verlag Stuttgart.
