Check Digit Verification of cas no

The CAS Registry Mumber 74087-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,8 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74087-87:
(7*7)+(6*4)+(5*0)+(4*8)+(3*7)+(2*8)+(1*7)=149
149 % 10 = 9
So 74087-87-9 is a valid CAS Registry Number.

A Fourier Transform Infrared Study of the Kinetics and Mechanism for the Reaction HO + CH3OOH

Niki, H.,Maker, P. D.,Savage,C. M.,Breitenbach, L. P.

, p. 2190 - 2193 (2007/10/02)

The analysis of products in the photolysis of mixtures containing C2H5ONO, NO, and CH3OOH in ppm concentrations in 700 torr of O2-N2 diluent by FT IR is consistent with a value of (k1a/k1b) = 0.77 (+/-20percent) for the competitive H-abstraction channels HO + CH3OOH -> CH2OOH + H2O (1a) and -> CH3OO + H2O (1b).An absolute value of (k1a + k1b) = 1.0 * 10-11 cm3 molecule-1 s-1 was derived from the decay rates of CH3OOH relative to those of C2H4 and CH3CHO.
