Check Digit Verification of cas no

The CAS Registry Mumber 641613-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,1,6,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 641613-89:
(8*6)+(7*4)+(6*1)+(5*6)+(4*1)+(3*3)+(2*8)+(1*9)=150
150 % 10 = 0
So 641613-89-0 is a valid CAS Registry Number.

A Facile Synthesis of 2,4-Disubstituted 3-Fluoroquinolines via Intramolecular Cyclization of o-Cyanomethylamino-β,β-difluorostyrenes

Wada, Yukinori,Mori, Takashi,Ichikawa, Junji

, p. 1000 - 1001 (2003)

o-Cyanomethylamino-β,β-difluorostyrenes are treated with base (LiTMP, NaH, or K2CO3) to generate the corresponding carbanions, which in turn readily undergo intramolecular replacement of the vinylic fluorine and subsequent eliminatio
