99705-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99705-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,0 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99705-36:
(7*9)+(6*9)+(5*7)+(4*0)+(3*5)+(2*3)+(1*6)=179
179 % 10 = 9
So 99705-36-9 is a valid CAS Registry Number.

The efficient synthesis of chiral key intermediates for monobactam antibiotics
Nishida,Shibasaki,Ikegami
, p. 765 - 768 (2007/10/02)
Chemical asymmetric syntheses of the key intermediates (4,6,8) for the synthesis of monobactam antibiotics (SQ 26776 (azthreonam, sulfazecin, and SQ 26180) are accomplished from (±)-4-phenylsulfonyl-2-azetidinone.
