90581-08-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90581-08-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,8 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90581-08:
(7*9)+(6*0)+(5*5)+(4*8)+(3*1)+(2*0)+(1*8)=131
131 % 10 = 1
So 90581-08-1 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.
