876174-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 876174-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,6,1,7 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 876174-66:
(8*8)+(7*7)+(6*6)+(5*1)+(4*7)+(3*4)+(2*6)+(1*6)=212
212 % 10 = 2
So 876174-66-2 is a valid CAS Registry Number.

Synthesis of enantiopure tricarbonyl(indan-1,2-dione)chromium
Leinweber, Dirk,Weidner, Ingo,Wilhelm, Rene,Wartchow, Rudolf,Butenschoen, Holger
, p. 5224 - 5235 (2005)
A multistep synthesis of the planar chiral tricarbonyl(η6- indan-1,2-dione)chromium, based on acetal protection of the keto groups, is presented. Since common deacetalization procedures failed, an oxidative deprotection with triphenylcarbenium
