Check Digit Verification of cas no
The CAS Registry Mumber 433335-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,3,3 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 433335-07:
(8*4)+(7*3)+(6*3)+(5*3)+(4*3)+(3*5)+(2*0)+(1*7)=120
120 % 10 = 0
So 433335-07-0 is a valid CAS Registry Number.

An expeditious one-pot synthesis of diethyl N-Boc-1-aminoalkylphosphonates
Klepacz, Anna,Zwierzak, Andrzej
, p. 1079 - 1080 (2007/10/03)
A general one-pot, purification-free synthesis of diethyl N-Boc-1-aminoalkylphosphonates has been developed. The procedure involves base-catalyzed Michael-type addition of sodium diethyl phosphite to N-Boc imines generated in situ by the action of sodium
