904893-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904893-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,8,9 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 904893-28:
(8*9)+(7*0)+(6*4)+(5*8)+(4*9)+(3*3)+(2*2)+(1*8)=193
193 % 10 = 3
So 904893-28-3 is a valid CAS Registry Number.

, p. 6979 - 6981 (2007/10/03)
The synthesis of a chiral cyclic nitrone with l-arabino configuration and its application in the total synthesis of radicamine B is reported. An agreement in the spectral data with natural radicamine B but specific rotation with an opposite sign warranted
