Check Digit Verification of cas no

The CAS Registry Mumber 838827-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,8,8,2 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 838827-31:
(8*8)+(7*3)+(6*8)+(5*8)+(4*2)+(3*7)+(2*3)+(1*1)=209
209 % 10 = 9

Synthesis of a bifunctional boron-Lewis acid and studies on host-guest chemistry using pyridine and TMPD

Rudlof, Jens,Neumann, Beate,Stammler, Hans-Georg,Mitzel, Norbert W.

, p. 141 - 148 (2021/12/27)

Based on the previously described bifunctional Lewis acid with a functional distance of the boron functions of 4.918(2) ?, the development of a further bifunctional, boron-containing Lewis acid with a wider functional distance is demonstrated. Again, a st
