Check Digit Verification of cas no

The CAS Registry Mumber 65500-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65500-65:
(7*6)+(6*5)+(5*5)+(4*0)+(3*0)+(2*6)+(1*5)=114
114 % 10 = 4
So 65500-65-4 is a valid CAS Registry Number.

Structure-reactivity relationship in the reaction of highly reactive zinc with alkyl bromides

Guijarro, Albert,Rieke, Reuben D.

, p. 1679 - 1681 (2007/10/03)

Zinc is different! Unlike with magnesium or lithium, the reactions of organic bromides with highly reactive zinc (Zn*) show sensitivity for the structure of the organic moiety. Selective insertions of Zn into tertiary C-Br bonds can be achieved [Eq. (a)]. Competitive kinetic techniques were used to quantify these findings.
