Check Digit Verification of cas no

The CAS Registry Mumber 137777-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,7 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137777-10:
(8*1)+(7*3)+(6*7)+(5*7)+(4*7)+(3*7)+(2*1)+(1*0)=157
157 % 10 = 7
So 137777-10-7 is a valid CAS Registry Number.

Rearrangements of Pyrrole and Indole Substituted Enol Esters of Cyclohexane-1,3-dione

Oliver, James E.,Lusby, William R.,Waters, Rolland M.

, p. 1565 - 1568 (2007/10/02)

Enol esters 3a and 3b, from cyclohexane-1,3-dione and pyrrole-2-carbonyl chloride and indole-2-carbonyl chloride, respectively, rearranged in the presence of triethylamine to the enamino acids 7 and 12.In the presence of cyanide, 3b, also underwent the expected rearrangement to 4b, whereas only 7 was formed from 3a.Treatment of 7 with mercuric acetate in hot acetic acid resulted in decarboxylation and aromatization to phenol 9.
