Check Digit Verification of cas no

The CAS Registry Mumber 52086-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,8 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52086-50:
(7*5)+(6*2)+(5*0)+(4*8)+(3*6)+(2*5)+(1*0)=107
107 % 10 = 7
So 52086-50-7 is a valid CAS Registry Number.

Nickel-Catalyzed Benzylic Substitution of Benzyl Esters with Malonates as a Soft Carbon Nucleophile

Tsuji, Hiroaki,Hashimoto, Keisuke,Kawatsura, Motoi

, p. 8837 - 8841 (2019/11/11)

The nickel-catalyzed benzylic substitution of benzyl alcohol derivatives with a soft carbon nucleophile is extremely rare compared to that with a hard carbon nucleophile. We have achieved the nickel-catalyzed benzylic substitution of benzyl esters with malonates as a soft carbon nucleophile. Primary and secondary benzyl 2,3,4,5,6-pentafluorobenzoates as well as a wide variety of malonate derivatives were well tolerated in the nickel-catalyzed reaction, providing the corresponding alkylation products in 46-86% yields (34 examples). Additionally, we propose a possible reaction mechanism that would undergo via the ??1- A nd ??3-benzylnickel intermediates.
