137204-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137204-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137204-76:
(8*1)+(7*3)+(6*7)+(5*2)+(4*0)+(3*4)+(2*7)+(1*6)=113
113 % 10 = 3
So 137204-76-3 is a valid CAS Registry Number.

Stereoselective syntheses of bridgehead hydroxy compounds via reductive cyclization reactions promoted by samarium diiodide
Hon,Lu,Chu
, p. 1981 - 1988 (2007/10/02)
Cycloalkanones appended with an α,β-unsaturated carbonyl side chain react with 2.25 equivalents of samarium diiodide to form bicyclic or tricyclic bridgehead hydroxy compounds stereoselectivity in moderate yield.
