1310803-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1310803-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,8,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1310803-45:
(9*1)+(8*3)+(7*1)+(6*0)+(5*8)+(4*0)+(3*3)+(2*4)+(1*5)=102
102 % 10 = 2
So 1310803-45-2 is a valid CAS Registry Number.

Ring strain-promoted allylic transposition of cyclic silyl ethers
Volchkov, Ivan,Park, Sangho,Lee, Daesung
, p. 3530 - 3533 (2011/09/15)
Relief of the ring strain of medium-sized rings promotes a regioselective allylic transposition of a C-O bond when catalyzed by rhenium oxide. Through the allylic transposition, eight-membered cyclic silyl ethers undergo ring contraction to the corresponding six-membered siloxacycles.
