Check Digit Verification of cas no
The CAS Registry Mumber 201858-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,5 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201858-22:
(8*2)+(7*0)+(6*1)+(5*8)+(4*5)+(3*8)+(2*2)+(1*2)=112
112 % 10 = 2
So 201858-22-2 is a valid CAS Registry Number.

Novel one-pot Mannich-type reaction in water: Indium trichloride-catalyzed condensation of aldehydes, amines and silyl enol ethers for the synthesis of β-amino ketones and esters
Loh, Teck-Peng,Wei, Lin-Li
, p. 323 - 326 (1998)
Novel one-pot Mannich-type reaction between aldehydes, amines and silyl enol ethers is catalyzed by indium trichloride in water to give β-amino ketones and esters in moderate to good yields.
