Check Digit Verification of cas no

The CAS Registry Mumber 244233-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,3 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 244233-48:
(8*2)+(7*4)+(6*4)+(5*2)+(4*3)+(3*3)+(2*4)+(1*8)=115
115 % 10 = 5
So 244233-48-5 is a valid CAS Registry Number.

Stereoselectivity, periselectivity and regioselectivity in the intramolecular cycloadditions of heptafulvene-fulvenes

Liu, Ching-Yang,Shie, Huei-Yan,Yu, Chien-Liang

, p. 9171 - 9184 (1999)

The side-chain and substituent control of stereoselectivity, periselectivity and regioselectivity in the intramolecular [8 + 6] and [4 + 2] cycloadditions of electron-deficient 8-cyanoheptafulvenes connected at C- 8 by trimethylene or tetramethylene chains to C-6 of electron-rich 6-methyl- or 6-phenylfulvenes are discussed.
