1187817-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187817-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,8,1 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1187817-52:
(9*1)+(8*1)+(7*8)+(6*7)+(5*8)+(4*1)+(3*7)+(2*5)+(1*2)=192
192 % 10 = 2
So 1187817-52-2 is a valid CAS Registry Number.

Ytterbium (III) triflate catalysed [3 + 2] cycloaddition involving isothiocyanates and epichlorohydrin
Xie, Yuanyuan,Chen, Xiaodong,Su, Weike
scheme or table, p. 129 - 132 (2009/10/15)
Highly regioselective cycloadditions occur in reactions of substituted isothiocyanates and epichlorohydrin to give N-(5-(chloromethyl)-1,3-oxathiolan- 2-ylidene)anilines catalysed by Yb(OTf)3. The configuration is retained at the chiral centres
