Check Digit Verification of cas no

The CAS Registry Mumber 21519-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,1 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21519-52:
(7*2)+(6*1)+(5*5)+(4*1)+(3*9)+(2*5)+(1*2)=88
88 % 10 = 8
So 21519-52-8 is a valid CAS Registry Number.

Nickel-Catalyzed Selective Reduction of Carboxylic Acids to Aldehydes

Iosub, Andrei V.,Morav?ík, ?tefan,Wallentin, Carl-Johan,Bergman, Joakim

, p. 7804 - 7808 (2019)

The direct reduction of carboxylic acids to aldehydes is a fundamental transformation in organic synthesis. The combination of an air-stable Ni precatalyst, dimethyl dicarbonate as an activator, and silane reductant effects this reduction for a wide variety of substrates, including pharmaceutically relevant structures, in good yields and with no overreduction to alcohols. Moreover, this methodology is scalable, allows access to deuterated aldehydes, and is also compatible with one-pot utilization of the aldehyde products.
