Check Digit Verification of cas no

The CAS Registry Mumber 182998-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,9,9 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 182998-40:
(8*1)+(7*8)+(6*2)+(5*9)+(4*9)+(3*8)+(2*4)+(1*0)=189
189 % 10 = 9
So 182998-40-9 is a valid CAS Registry Number.

Enantiomerically pure α-fluoroalkyl-α-amino acids: Synthesis of (R)-α-difluoromethyl-alanine and (S)-α-difluoromethyl-serine

Bravo, Pierfrancesco,Capelli, Silvia,Meille, Stefano V.,Seresini, Paolo,Volonterio, Alessandro,Zanda, Matteo

, p. 2321 - 2332 (2007/10/03)

Hydrocyanation of enantiomerically pure N-Cbz α-fluoroalkyl β-sulfinylenamines 1 occurs smoothly by treatment with KCN or by addition of trimethylsilylcyanide or diethyl phosphorocyanidate to preformed sodium derivatives of 1. The diastereoisomeric difluoro α-aminonitriles 2b have been transformed in the unnatural amino acids (R)-α-difluoromethyl-alanine and (S)-α-difluoromethyl-serine.
