Check Digit Verification of cas no

The CAS Registry Mumber 864277-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,2,7 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 864277-08:
(8*8)+(7*6)+(6*4)+(5*2)+(4*7)+(3*7)+(2*0)+(1*8)=197
197 % 10 = 7
So 864277-08-7 is a valid CAS Registry Number.

In a flow microreactor, aryllithiums bearing a piperidylmethyl group were generated using nBuLi by precise residence time control and effective temperature control, and then selectively borylated with boronic esters such as 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (BpinOiPr) and trimethyl borate B(OMe)3 by fast mixing. Moreover, the direct integration with Suzuki–Miyaura cross coupling were successfully achieved to obtain nitrogen-containing biaryl compounds. The present method could be applied for the straightforward synthesis of the key intermediate of a bioactive component bearing a piperidylmethyl-biphenyl framework.
