Check Digit Verification of cas no
The CAS Registry Mumber 849440-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,4,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 849440-31:
(8*8)+(7*4)+(6*9)+(5*4)+(4*4)+(3*0)+(2*3)+(1*1)=189
189 % 10 = 9
So 849440-31-9 is a valid CAS Registry Number.

Ouchi, Hidekazu,Kumagai, Midori,Sakurada, Shinobu,Takahata, Hiroki
, p. 505 - 514 (2007/10/03)
All possible regioisomers of dimethyl-substituted (S)-phenylalanine were efficiently synthesized by reacting the Ni(II)-complex of the chiral Schiff base of glycine with (S)-2-N-(N-benzylprolyl)-aminobenzophenone.
