158697-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158697-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,9 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158697-19:
(8*1)+(7*5)+(6*8)+(5*6)+(4*9)+(3*7)+(2*1)+(1*9)=189
189 % 10 = 9
So 158697-19-9 is a valid CAS Registry Number.

Synthesis and Herbicidal Activity of Phenylproparginols
Parlow, John J.,Clark, Robert D.
, p. 2600 - 2609 (2007/10/02)
A three-step/one-pot procedure was developed for preparing herbicidal fluorophenylproparginols from acetophenones by way of an enol phosphate intermediate.Side-by-side testing of 16 of the more active analogs showed that trans-2-methyl-1-2-(4-methoxy-2,3
