158504-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158504-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,0 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158504-99:
(8*1)+(7*5)+(6*8)+(5*5)+(4*0)+(3*4)+(2*9)+(1*9)=155
155 % 10 = 5
So 158504-99-5 is a valid CAS Registry Number.

REDUCTION OF α-ALKYNYL EPOXIDES
Vasil'ev, A. A.
, p. 38 - 41 (2007/10/02)
The catalytic hydrogenation of 2-(1-heptynyl)oxirane leads preferentially to 3(Z)-nonen-1-ol, whereas the reduction of this epoxide with lithium in ethylamine gives 3(E)-nonen-1-ol.In both cases the main products are accompanied by the isomeric 2-nonen-1-ols.
