Check Digit Verification of cas no

The CAS Registry Mumber 1231257-90-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,2,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1231257-90:
(9*1)+(8*2)+(7*3)+(6*1)+(5*2)+(4*5)+(3*7)+(2*9)+(1*0)=121
121 % 10 = 1
So 1231257-90-1 is a valid CAS Registry Number.

Amide Effects in C?H Activation: Noncovalent Interactions with L-Shaped Ligand for meta Borylation of Aromatic Amides

Bisht, Ranjana,Hoque, Md Emdadul,Chattopadhyay, Buddhadeb

supporting information, p. 15762 - 15766 (2018/11/10)

A new concept for the meta-selective borylation of aromatic amides is described. It has been demonstrated that while esters gave para borylations, amides lead to meta borylations. For achieving high meta selectivity, an L-shaped bifunctional ligand has been employed and engages in an O???K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction provides exceptional control for meta C?H activation/borylation.
