Check Digit Verification of cas no

The CAS Registry Mumber 82053-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,5 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82053-85:
(7*8)+(6*2)+(5*0)+(4*5)+(3*3)+(2*8)+(1*5)=118
118 % 10 = 8
So 82053-85-8 is a valid CAS Registry Number.

Longifolene-Derived Amines: A Comparative Hofmann Elimination Study with Isolongifolic Acid and Homoisolongifolic Acid as Precursors

Shitole, H. R.,Nayak, U. R.

, p. 88 - 90 (2007/10/02)

Isolongifolic acid (2) and homoisolongifolic acid (3) have been transformed into the C15- and C16-N,N-dimethylamino derivatives (8) and (9), respectively.A comparative Hofmann elimination study has revealed that, although both 8 and 9 possess a β-hydrogen available for elimination, the product-outcome is significantly different in the two cases; the major compound in the case of 8 arises from a reversal of the quaternary base to the parent dimethylamine (54percent) although a trivial amount (10percent) of the expected longifolene is also formed; on the other hand, 9 generates the theoretically anticipated vinylnorlongifolane (13) in 37 percent yield comparable with that of the dimethylamine (9) (33percent).Pb(IV)-Cu(II) reaction on the primary acid (3) fails to give longifolene by oxidative decarboxylation.
