Check Digit Verification of cas no

The CAS Registry Mumber 120316-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,1 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120316-39:
(8*1)+(7*2)+(6*0)+(5*3)+(4*1)+(3*6)+(2*3)+(1*9)=74
74 % 10 = 4
So 120316-39-4 is a valid CAS Registry Number.

Mechanism of an Interesting Ring-Contraction Reaction of a Class of Carbocyclic trans-Dibromides and Stereoisomeric Bromohydrins through Solvolysis

Mandal, Asok N.,Bhattacharya, Sudin,Raychaudhuri, Swadesh R.,Chatterjee, Amareshwar

, p. 2856 - 2876 (2007/10/02)

An efficient ring contraction of the trans-dibromides and the bromohydrins (1a-f) through solvolysis under neutral conditions to the aldehydes (3a-d) in good to excellent yields is reported.The role of substituent, influence of stereochemistry, and the effect of ring size on the case of this interesting ring contraction reaction are clearly demonstrated from the results, tabulated in Table 1; a probable mechanism for ring contraction is presented.
