Check Digit Verification of cas no

The CAS Registry Mumber 72586-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,8 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72586-44:
(7*7)+(6*2)+(5*5)+(4*8)+(3*6)+(2*4)+(1*4)=148
148 % 10 = 8
So 72586-44-8 is a valid CAS Registry Number.

Chelation-directed remote: Meta -C-H functionalization of aromatic aldehydes and ketones

Xie, Shuguang,Li, Sen,Ma, Wenqian,Xu, Xiaohua,Jin, Zhong

supporting information, p. 12408 - 12411 (2019/10/19)

We disclose herein the development of a versatile 1,2-diol directing template for palladium-catalyzed remote meta-C-H functionalization of aromatic aldehydes and ketones. In situ-generation of acetals and ketals, as well as removal afterwards, makes the C-H bond functionalization process more straightforward and efficient. This also represents the first example of chelation-directed meta-C-H functionalization of aromatic aldehydes and ketones.
