Check Digit Verification of cas no

The CAS Registry Mumber 53629-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,2 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53629-44:
(7*5)+(6*3)+(5*6)+(4*2)+(3*9)+(2*4)+(1*4)=130
130 % 10 = 0
So 53629-44-0 is a valid CAS Registry Number.

Synthesis of 8-oxoberbines and related benzolactams by Pd(OAc) 2-catalyzed direct aromatic carbonylation

, p. E48-E54 (2013)

A variety of alkoxy-substituted benzolactams with a berbine or yohimbane skeleton were prepared from 1-benzyl-1,2,3,4-tetrahydroisoquinolines or 1-benzyl-1,2,3,4-tetrahydro-β-carbolines by a phosphine-free Pd(II)-catalyzed direct aromatic carbonylation in a Pd(OAc)2-Cu(OAc) 2 catalytic system. The site selectivity was compared with that of the carbonylation with Pd(OAc)2 or Pd(OAc)2·2 PPh3, respectively.
