147727-75-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147727-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,2 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 147727-75:
(8*1)+(7*4)+(6*7)+(5*7)+(4*2)+(3*7)+(2*7)+(1*5)=161
161 % 10 = 1
So 147727-75-1 is a valid CAS Registry Number.

Ring Expansions of Alkynyl Cyclopentanols with Iodine and Koser's Reagent.
Bovonsombat, Pakorn,McNelis, Edward
, p. 1525 - 1534 (2007/10/02)
Equimolecular amounts of iodine, Koser's reagent, and 1-bromoethynylcyclopentanols with none, one or two methyl groups in the α-position lead to ring expansions in acetonitrile at room temperature in yields of 75 to 85percent.In the so-formed 2-bromoiodo
