Check Digit Verification of cas no

The CAS Registry Mumber 857805-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,8,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 857805-53:
(8*8)+(7*5)+(6*7)+(5*8)+(4*0)+(3*5)+(2*5)+(1*3)=209
209 % 10 = 9
So 857805-53-9 is a valid CAS Registry Number.

, p. E48-E54 (2013/06/05)

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.
