Check Digit Verification of cas no

The CAS Registry Mumber 42235-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,3 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42235-39:
(7*4)+(6*2)+(5*2)+(4*3)+(3*5)+(2*3)+(1*9)=92
92 % 10 = 2
So 42235-39-2 is a valid CAS Registry Number.

Ito, Yosuke,Tomiyasu, Yuichi,Kawanabe, Takahiro,Uemura, Keisuke,Ushimizu, Yuu,Nishino, Hiroshi

supporting information; scheme or table, p. 1491 - 1507 (2011/04/23)

Cyclophane-type macrocyclic compounds from 21 to 56 members having two fused dihydrofuran rings were synthesized by the manganese(iii)-mediated oxidation of terminal dienes with bis(3-oxobutanoate)s containing aromatics. The reaction detail, characterization and reaction pathways are described. The Royal Society of Chemistry 2011.
