Check Digit Verification of cas no

The CAS Registry Mumber 177982-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,9,8 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 177982-77:
(8*1)+(7*7)+(6*7)+(5*9)+(4*8)+(3*2)+(2*7)+(1*7)=203
203 % 10 = 3
So 177982-77-3 is a valid CAS Registry Number.

Accidental discovery of a 'longer-range' vinylogous Pummerer-type lactonization: Formation of sulindac sulfide lactone from sulindac

Halder, Somnath,Satyam, Apparao

, p. 1179 - 1182 (2011)

Unexpected formation of sulindac sulfide lactone occurred when sulindac was treated with oxalyl chloride and triethylamine. Structurally analogous sulindac sulfide and indomethacin did not undergo such lactonization under similar reaction conditions. We b
