70250-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70250-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,5 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70250-63:
(7*7)+(6*0)+(5*2)+(4*5)+(3*0)+(2*6)+(1*3)=94
94 % 10 = 4
So 70250-63-4 is a valid CAS Registry Number.

Formation of Lactones via a Radical Ring Closure Mechanism
Beckwith, Athelstan L. J.,Pigou, Paul E.
, p. 85 - 86 (2007/10/02)
Suitable alkenoyloxymethyl iodides or selenides are converted into lactones upon treatment with tributyl-stannane or -germane; the reaction involves highly regioselective and stereoselective ring closure of alkenoyloxymethyl radicals (1).
