The CAS Registry Mumber 699023-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,9,0,2 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 699023-60:
(8*6)+(7*9)+(6*9)+(5*0)+(4*2)+(3*3)+(2*6)+(1*0)=194
194 % 10 = 4
So 699023-60-4 is a valid CAS Registry Number.

Palladium-catalyzed [3,3] sigmatropic rearrangement of (allyloxy) iminodiazaphospholidines: Allylic transposition of C-O and C-N functionality

Lee, Ernest E.,Batey, Robert A.

, p. 1865 - 1868 (2004)

A PV=N to PV=O interconversion is the thermodynamic driving force for the title reaction. Iminodiazaphospholidines 1 give phosphoramides 2, which are subsequently hydrolyzed under mild acidic conditions to yield primary or tosylamines 3. R = alkyl, phenyl; Ts = p-toluenesulfonyl.
