Check Digit Verification of cas no

The CAS Registry Mumber 145057-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145057-99:
(8*1)+(7*4)+(6*5)+(5*0)+(4*5)+(3*7)+(2*9)+(1*9)=134
134 % 10 = 4
So 145057-99-4 is a valid CAS Registry Number.

An Efficient and Practical Synthesis of L-α-Amino Acids Using (R)-Phenylglycinol as a Chiral Auxiliary

Inaba, Takashi,Kozono, Ichiro,Fujita, Makoto,Ogura, Katsuyuki

, p. 2359 - 2365 (2007/10/02)

L-α-Amino acids including L-α-arylglycines were conveniently and stereoselectively synthesized via the α-amino carbonitriles given by the Strecker reaction of (R)-2-amino-2-phenylethanol with aldehydes and hydrogen cyanide.The stereoselectivity of these α-amino carbonitriles was thermodynamically controlled.
