82891-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82891-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,9 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82891-86:
(7*8)+(6*2)+(5*8)+(4*9)+(3*1)+(2*8)+(1*6)=169
169 % 10 = 9
So 82891-86-9 is a valid CAS Registry Number.

Transamidation of thioamides with 2-aminoethanol, followed by cyclodehydrosulfurisation of the resultant N-(β-hydroxyethyl)thioamides, has been utilised for the mild and efficient synthesis of 2-oxazolines. The developed protocol was found to be of general applicability. Georg Thieme Verlag KG Stuttgart · New York.
