Check Digit Verification of cas no

The CAS Registry Mumber 103677-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,7 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103677-62:
(8*1)+(7*0)+(6*3)+(5*6)+(4*7)+(3*7)+(2*6)+(1*2)=119
119 % 10 = 9
So 103677-62-9 is a valid CAS Registry Number.

Hydrogenolysis of the C-O Bond of the 1,2,4-Oxadiazine Ring. Adams Platinum Hydrogenation of 3-Aryl-5,6-dihydro-5-(substituted)-methylene-4H-1,2,4-oxadiazine Derivatives

Kawashima, Etsuko,Takada, Toyozo,Tabei, Katsumi

, p. 1409 - 1412 (2007/10/02)

Adams platinum hydrogenation of Z-3-aryl-5,6-dihydro-5-(substituted)methylene-4H-1,2,4-oxadiazine (1a-f) proceeds very slowly through C-O bond fission to give N-(1-substitutedcarbonyl-2-propylidene)benzamide oxime derivative 2 as the main product.In the reaction of 5-(arylcarbamoyl)methylene analogues 1d-f, 5-(arylcarbamoyl)methyl-5,6-dihydro-3-phenyl-4H-1,2,4-oxadiazine (4) and N-aryl-3-hydroxybutanamide derivative 5 are also obtained as well as compound 2.
