Check Digit Verification of cas no

The CAS Registry Mumber 75511-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,1 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75511-31:
(7*7)+(6*5)+(5*5)+(4*1)+(3*1)+(2*3)+(1*1)=118
118 % 10 = 8
So 75511-31-8 is a valid CAS Registry Number.

Photosolvolysis of O,O,S-Trimethyl Phosphorodithioate. Evidence for an SN1(P) Mechanism

Benschop, Hendrik P.,Konings, Cornelis A. G.,Platenburg, Dominique H. J. M.,Deen, Rudolf

, p. 370 - 372 (1980)

Irradiation (254 nm) of (MeO)2P(S)SMe in ROH yields mainly (66 percent, R = Pri) the ionic photosolvolysis product (MeO)2P(S)OR with very low capture ratio 1.9 +/- 0.4 for R = Me vs.R = Pri under competitive photosolvolysis conditions, whereas irradiation in e.g. tetrahydrofuran and CH2Cl2 gives free-radical products, suggesting that the photoreactions proceed by way of an 'intimate radical-ion pair.'
