902451-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 902451-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,4,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 902451-82:
(8*9)+(7*0)+(6*2)+(5*4)+(4*5)+(3*1)+(2*8)+(1*2)=145
145 % 10 = 5
So 902451-82-5 is a valid CAS Registry Number.

, p. 4429 - 4438 (2008/02/02)
Stereoselective synthesis of an immunomodulator (+)-conagenin was achieved. Both amine and carboxylic acid moieties were prepared from commercially available optically active methyl 3-hydroxy-2-methylpropanoate using dirhodium(II)-catalyzed C-H amination
