Check Digit Verification of cas no

The CAS Registry Mumber 1126527-58-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,5,2 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1126527-58:
(9*1)+(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*7)+(2*5)+(1*8)=139
139 % 10 = 9
So 1126527-58-9 is a valid CAS Registry Number.

Trifluoroethanol as an efficient reaction media for the synthesis of pyran skeleton through domino Knoevenagel-hetero-Diels-Alder reaction with non-activated alkynes

Balalaie, Saeed,Azizian, Javad,Shameli, Abolghasem,Bijanzadeh, Hamid Reza

, p. 631 - 637 (2015/02/19)

Trifluoroethanol as an efficient media for the domino Knoevenagel-hetero-Diels-Alder reaction of O-propargyloxy benzaldehydes as non-activated terminal alkynes with some active methylene compounds has been described. Short reaction time, easy work-up, good to high yields, and mild reaction conditions are advantages of this new media. Graphical Abstract: [Figure not available: see fulltext.]
