172687-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172687-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,8 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 172687-22:
(8*1)+(7*7)+(6*2)+(5*6)+(4*8)+(3*7)+(2*2)+(1*2)=158
158 % 10 = 8
So 172687-22-8 is a valid CAS Registry Number.

An Efficient and Versatile Method for the Preparation of α-Keto Acid Derivatives from Terminal Alkenes
Hon, Yung-Son,Lin, Wei-Chih
, p. 7693 - 7696 (2007/10/02)
Ozonolysis of terminal alkenes followed by reacting with a preheated mixture of CH2Br2-Et2NH affords α-substituted acroleins, which can be converted to α-keto acid derivatives in three steps, under very mild reaction conditions.
