Check Digit Verification of cas no

The CAS Registry Mumber 249291-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,2,9 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 249291-84:
(8*2)+(7*4)+(6*9)+(5*2)+(4*9)+(3*1)+(2*8)+(1*4)=167
167 % 10 = 7
So 249291-84-7 is a valid CAS Registry Number.

The Pd-cataylsed direct ortho-C(sp2)-H fluorination of aromatic ketones has been developed for the first time. The reaction features good regioselectivity and simple operations, constituting an alternative shortcut to access fluorinated ketones. A concise synthesis of anacetrapib has also been achieved by using late-stage C-H fluorination as a key step.
