Check Digit Verification of cas no

The CAS Registry Mumber 74813-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74813-20:
(7*7)+(6*4)+(5*8)+(4*1)+(3*3)+(2*2)+(1*0)=130
130 % 10 = 0
So 74813-20-0 is a valid CAS Registry Number.

STUDIES IN SESQUITERPENES-LV ISOLONGIFOLENE(PART 6): MECHANISM OF REARRANGEMENT OF LONGIFOLENE TO ISOLONGIFOLENE-I

Yadav, J. S.,Nayak, U. R.,Dev, Sukh

, p. 309 - 315 (2007/10/02)

The gross mechanism of rearrangement of longifolene to isolongifolene has been elucidated by using site-specifically labelled longifolene-4,4,5,5-d4 and shown to follow the pathway proposed by Berson et al., which involves an exo, exo Me shift, in preference to the endo, endo Me migration route proposed earlier.An efficient synthesis of longifolene-4,4,5,5-d4, the key compound in the present investigation, is described.
