220586-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220586-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,8 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220586-50:
(8*2)+(7*2)+(6*0)+(5*5)+(4*8)+(3*6)+(2*5)+(1*0)=115
115 % 10 = 5
So 220586-50-5 is a valid CAS Registry Number.

Asymmetric synthesis of aziridine 2-phosphonates and azirinyl phosphonates from enantiopure sulfinimines
Davis,McCoull
, p. 249 - 252 (1999)
Enantiopure sulfinimine (S)-4 was employed in a Darzens-type synthesis of aziridine 2-phosphonates (-)-7/(+)-8 which were transformed into α-amino phosphonates (S)-11/(R)-12 and the first enantiopure examples of azirinyl phosphonates 13-15.
