Check Digit Verification of cas no
The CAS Registry Mumber 54396-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,9 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54396-69:
(7*5)+(6*4)+(5*3)+(4*9)+(3*6)+(2*6)+(1*9)=149
149 % 10 = 9
So 54396-69-9 is a valid CAS Registry Number.

Cycloadditions of dialkyl thioketone-S-methylides
Huisgen,Mloston
, p. 7041 - 7044 (1989)
Various mechanistic criteria were employed in the effort to establish the borderline between one-step and two-step pathways in the reactions of two thiocarbonyl ylides, diisopropyl, and di-ter-butyl thioketone-S-methylide, with electron-deficient alkenes
