Check Digit Verification of cas no

The CAS Registry Mumber 78946-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,4 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78946-48:
(7*7)+(6*8)+(5*9)+(4*4)+(3*6)+(2*4)+(1*8)=192
192 % 10 = 2
So 78946-48-2 is a valid CAS Registry Number.

A NOVEL FIVE-CARBON HOMOLOGATION LEADING TO 3,4-ALKADIENOIC ACIDS BY SN2' REACTION OF β-ETHYNYL-β-PROPIOLACTONE WITH GRIGNARD REAGENTS IN THE PRESENCE OF COPPER(I) CATALYST

Sato, Toshio,Kawashima, Masatoshi,Fujisawa, Tamotsu

, p. 2375 - 2378 (2007/10/02)

β-Ethynyl-β-propiolactone reacts regioselectively with Grignard reagents in the presence of copper(I) catalyst to afford 3,4-alkadienoic acids in high yields.Synthetic utility of this reaction is demonstrated in the simple synthesis of pellitorine.
