86560-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86560-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,6 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86560-20:
(7*8)+(6*6)+(5*5)+(4*6)+(3*0)+(2*2)+(1*0)=145
145 % 10 = 5
So 86560-20-5 is a valid CAS Registry Number.

Aroylspirobutenolides and their reduced derivatives: New analgesic compounds
Paris,Payard,Tronche,et al.
, p. 147 - 150 (2007/10/02)
Acylation of benzene or its substituted derivatives with spirolactone 3-carboxylic acid chlorid provided nine new carbonylated compounds. Sodium borohydride quantitatively reduced the carbonyl group. All compounds are significant peripherical analgesics w
