Check Digit Verification of cas no

The CAS Registry Mumber 111733-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,3 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111733-88:
(8*1)+(7*1)+(6*1)+(5*7)+(4*3)+(3*3)+(2*8)+(1*8)=101
101 % 10 = 1
So 111733-88-1 is a valid CAS Registry Number.

Boranes in Synthesis. 2. Asymmetric Synthesis of β-Amino Alcohols. A Facile Conversion of 2-Amino Acetophenones to the Corresponding β-Amino Alcohols in High Enantiomeric Purity

Beardsley, David A.,Fisher, Gary B.,Goralski, Christian T.,Nicholson, Lawrence W.,Singaram, Bakthan

, p. 1511 - 1514 (1994)

The asymmetric reduction of 2-amino acetophenones with Ipc2BH or Ipc2BCl at -78 deg C, yields the corresponding β-amino alcohols in good to excellent yields.Although only modest (12-45percent ee) enantiomeric excesses were obtained with Ipc2BH, 75-99perce
