Check Digit Verification of cas no

The CAS Registry Mumber 1236879-90-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,8,7 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1236879-90:
(9*1)+(8*2)+(7*3)+(6*6)+(5*8)+(4*7)+(3*9)+(2*9)+(1*0)=195
195 % 10 = 5
So 1236879-90-5 is a valid CAS Registry Number.

Gold-catalyzed tandem cyclization of dienol silyl ethers for the preparation of bicyclo[4.3.0]nonane derivatives

Kusama, Hiroyuki,Karibe, Yusuke,Onizawa, Yuji,Iwasawa, Nobuharu

supporting information; experimental part, p. 4269 - 4272 (2010/08/07)

[Figure Presented] Tandem bicycle: A gold-catalyzed geminal carbo-functionalization reaction of 3-siloxy-1,3-dien-8-ynes proceeded smoothly to give bicyclo[4.3.0]nonanes stereoselectively through ring expansion of the bicyclic carbene complex intermediates. The product configuration was different from that of the thermal Diels-Alder adduct.
