Check Digit Verification of cas no

The CAS Registry Mumber 72548-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,4 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72548-21:
(7*7)+(6*2)+(5*5)+(4*4)+(3*8)+(2*2)+(1*1)=131
131 % 10 = 1

2. 2. 0.

Two new syntheses of cyclobutene esters and the use of 1-cyanocyclobutene as potential isoprene synthons are described. Photocycloaddition of methyl cyclobut-1-enecarboxylate and 1-cyanocyclobutene to piperitone, followed by reduction and lactonization, gives photodihydroarisolactone. Single-crystal X-ray analysis of the latter and a related compound reveals interesting structural features in the strained bicyclo left bracket 2. 2. 0 right bracket hexane system. Thermolysis of these lactones yields 1,5-cyclodecadienes related to germacrene sesquiterpenes.
