The CAS Registry Mumber 99381-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99381-85:
(7*9)+(6*9)+(5*3)+(4*8)+(3*1)+(2*8)+(1*5)=188
188 % 10 = 8
So 99381-85-8 is a valid CAS Registry Number.

Clayden, Jonathan,Collington, Eric W.,Egert, Ernst,McElroy, Andrew B.,Warren, Stuart

, p. 2801 - 2810 (2007/10/02)

Allylic phosphine oxides are epoxidised anti selectively by m-CPBA, but this selectivity can be reversed if the allylic phosphine oxide is also an allylic alcohol.
