Check Digit Verification of cas no

The CAS Registry Mumber 128011-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128011-31:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*1)+(2*3)+(1*1)=84
84 % 10 = 4
So 128011-31-4 is a valid CAS Registry Number.

ACID-CATALYZED TRANSFORMATIONS OF THE DERIVATIVES OF TERPENES IN THE BICYCLO- AND BICYCLOHEPTANE SERIES

Koval'skaya, S. S.,Kozlov, N. G.

, p. 1398 - 1407 (2007/10/03)

Under the conditions of acid catalysis the formation of the p-methane derivatives is the main direction in the transformations of pinane derivatives with reaction centers at C2 and C3 (α-pinene epoxide, 2α-hydroxypinan-3-one, 2α-hydroxypinan-3-one oxime, isopinocampheol and 3-phenylpinocampheol).Here, in the Ritter reaction thermodynamic factors give rise to the preferential formation of isomers with an equatorial acylamino group.The ability to react with nitriles under the conditions of acid catalysis with the formation of the geminal amides is a common feature of terpenoid ketones of the bicycloheptane series.The transformations of the terpenoid bicyclic oximes under the influence of sulfuric acid in aliphatic nitriles lead to the formation of two types of azabicyclic products - bicyclic lactams and bicyclic N-acylamidines.
