Check Digit Verification of cas no

The CAS Registry Mumber 150638-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,6,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 150638-80:
(8*1)+(7*5)+(6*0)+(5*6)+(4*3)+(3*8)+(2*8)+(1*0)=125
125 % 10 = 5
So 150638-80-5 is a valid CAS Registry Number.

HETEROCUMULENES IN ACYLATION REACTIONS. 1. MECHANISM OF ACID HYDROLYSIS OF 2,6,6-TRIMETHYL-1-CARBONYLCYCLOHEX-2-ENE AND ITS THIO AND N-ISOPROPYLIMINO ANALOGS

Lyashchuk, S. N.,Skrypnik, Yu. G.,Bezrodnyi, B. P.

, p. 109 - 114 (2007/10/02)

It was established that γ-protonation of the substrate takes place preferentially during the acid hydrolysis of 2,6,6-trimethyl-1-carbonylcyclohex-2-ene and its thio and N-isopropylimino analogs.The contribution from γ-protonation increases with increase in the polarity of the medium, the activity of H+, and the electronegativity of the heteroatom.The experimental results were confirmed by theoretical calculations (MNDO).
