Check Digit Verification of cas no

The CAS Registry Mumber 929539-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,5,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 929539-12:
(8*9)+(7*2)+(6*9)+(5*5)+(4*3)+(3*9)+(2*1)+(1*2)=208
208 % 10 = 8
So 929539-12-8 is a valid CAS Registry Number.

New approach to the synthesis of macrocyclic tetralactones via ring-closing metathesis using Grubbs' first-generation catalyst

Muthusamy, Sengodagounder,Gnanaprakasam, Boopathy,Suresh, Eringathodi

, p. 1495 - 1498 (2007/10/03)

(Chemical Equation Presented) A facile and efficient route to synthesize macrocyclic tetralactones with different ring sizes having a wide variety of spacers is described. The application of ring-closing metathesis for the synthesis of macrocyclic tetralactones is demonstrated with many examples in excellent yield. The representative structure of macrocyclic tetralactones is characterized by X-ray crystallography.
