Check Digit Verification of cas no
The CAS Registry Mumber 159453-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,4,5 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 159453-24:
(8*1)+(7*5)+(6*9)+(5*4)+(4*5)+(3*3)+(2*2)+(1*4)=154
154 % 10 = 4
So 159453-24-4 is a valid CAS Registry Number.

Example 14, (2010/01/31)
An industrially advantageous method of producing β-halogeno-α-aminocarboxylic acids is provided. Methods are also provided of producing optically active N-protected-S-phenylcysteines having high optical purity and of intermediates thereof, respectively, in which the above production method is utilized. A method of producing β-halogeno-α-aminocarboxylic acids or salts thereof is disclosed which comprises halogenating the hydroxyl group of a β-hydroxy-α-aminocarboxylic acid (in which the basicity of the amino group in α-position is not masked by the presence of a substituent on said amino group) or a salt thereof with an acid with a halogenating agent. A method of producing optically active N-protected-S-phenylcysteines represented by the general formula (3) or salts thereof is further disclosed which comprises applying the above production method to optically active serine or a salt thereof and then carrying out treatment with an amino-protecting agent and reaction with thiophenol under a basic condition.
