125340-81-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125340-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,4 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125340-81:
(8*1)+(7*2)+(6*5)+(5*3)+(4*4)+(3*0)+(2*8)+(1*1)=100
100 % 10 = 0
So 125340-81-0 is a valid CAS Registry Number.

Synthesis of a novel four-carbon chiron - (R)-1-t-butyldimethylsilyl-3,4-epoxy-but-1-yne
Lopp,Kanger,Muraus,Pehk,Lille
, p. 943 - 944 (1991)
A simple and efficient synthesis of the novel chiron-(R)-1-TBDMS-3,4-epoxy-but-1-yne has been developed starting from a derivative of (R,R)-(-)-tartaric acid. A new stereoselective bromination reaction of an O-silyl ether with BBr3 is also described.
