Check Digit Verification of cas no
The CAS Registry Mumber 53767-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,6 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53767-52:
(7*5)+(6*3)+(5*7)+(4*6)+(3*7)+(2*5)+(1*2)=145
145 % 10 = 5
So 53767-52-5 is a valid CAS Registry Number.

, p. 900 - 903 (2007/10/03)
Two new by-products, 17β-acetoxy-28-norlupane 6a and 17β-acetoxy-24,28-dinorlupane 6b have been identified from the oxidation of 28-lupanol 1a and 24-nor-28-lupanol 1b with lead tetraacetate, respectively. Pyrolysis of 6a or 6b at 225°C provides a mixture of 28-norlup-16-ene 2a (69%), 28-norlup-17-ene 4a (9%) and 28-norlup-17(22)-ene 3a (22%) or 24,28-dinorlup-16-ene 2b (70%), 24,28-dinorlup-17-ene 4b (8%) and 24,28-dinorlup-17(22)-ene 3b (22%).
