187728-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187728-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,7,2 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187728-34:
(8*1)+(7*8)+(6*7)+(5*7)+(4*2)+(3*8)+(2*3)+(1*4)=183
183 % 10 = 3
So 187728-34-3 is a valid CAS Registry Number.

POLYOL ETHERS AND PROCESS FOR MAKING THEM
-
Page/Page column 10, (2010/03/31)
New polyol ether compounds and a process for their preparation. The process comprises reacting a polyol, a carbonyl compound, and hydrogen in the presence of hydrogenation catalyst, to provide the polyol ether. The molar ratio of polyol to carbonyl compound in the process is greater than 5:1.
