Check Digit Verification of cas no

The CAS Registry Mumber 1424343-26-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,4,3,4 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1424343-26:
(9*1)+(8*4)+(7*2)+(6*4)+(5*3)+(4*4)+(3*3)+(2*2)+(1*6)=129
129 % 10 = 9
So 1424343-26-9 is a valid CAS Registry Number.

Palladium-Catalyzed Regioselective Aerobic Allylic C?H Oxygenation: Direct Synthesis of α,β-Unsaturated Aldehydes and Allylic Alcohols

supporting information, p. 1600 - 1604 (2018/03/05)

A protocol for the synthesis of α,β-unsaturated aldehydes and allylic alcohols from simple allylic hydrocarbons with water via palladium-catalyzed functionalization of allylic C?H bonds was described. Molecular oxygen is utilized as the sole oxidant in this oxygenation of terminal alkenes. This protocol features good functional group compatibility, broad substrate scope, and high atom- and step-economy. Moreover, the synthetic utility of this method can be highlighted by its application to the synthesis of ibuprofen, which is a highly potent analgesic. (Figure presented.).
