87220-50-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87220-50-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,2 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87220-50:
(7*8)+(6*7)+(5*2)+(4*2)+(3*0)+(2*5)+(1*0)=126
126 % 10 = 6
So 87220-50-6 is a valid CAS Registry Number.

BENZYLATION OF ALCOHOLS TO BENZYL ETHERS WITH ALKALI CATION EXCHANGED Y TYPE ZEOLITE

Onaka, Makoto,Kawai, Motomitsu,Izumi, Yusuke

, p. 1101 - 1104 (1983)

Benzylation of alcohols with benzyl chloride is found to proceed efficiently in the presence of alkali cation exchanged Y type zeolite in a non-polar solvent under neutral conditions.The effects in solvent and alkali cation of zeolite are studied.

NiH-Catalyzed Reductive Relay Hydroalkylation: A Strategy for the Remote C(sp3)?H Alkylation of Alkenes

Zhou, Fang,Zhu, Jin,Zhang, Yao,Zhu, Shaolin

supporting information, p. 4058 - 4062 (2018/03/21)

The terminal-selective, remote C(sp3)?H alkylation of alkenes was achieved by a relay process combining NiH-catalyzed hydrometalation, chain walking, and alkylation. This method enables the construction of unfunctionalized C(sp3)?C(sp3) bonds under mild conditions from two simple feedstock chemicals, namely olefins and alkyl halides. The practical value of this transformation is further demonstrated by the large-scale and regioconvergent alkylation of isomeric mixtures of olefins at low catalyst loadings.
