Check Digit Verification of cas no

The CAS Registry Mumber 1202407-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,4,0 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1202407-75:
(9*1)+(8*2)+(7*0)+(6*2)+(5*4)+(4*0)+(3*7)+(2*7)+(1*5)=97
97 % 10 = 7
So 1202407-75-7 is a valid CAS Registry Number.

Scandium-catalyzed regio- and stereospecific methylalumination of silyloxy/alkoxy-substituted alkynes and alkenes

Takimoto, Masanori,Usami, Saori,Hou, Zhaomin

supporting information; experimental part, p. 18266 - 18268 (2010/04/25)

(Chemical Equation Presented) Various alkynes and alkenes having a tethered ether group undergo methylalumination reactions with unprecedented regio- and stereoselectivity in the presence of a cationic half-sandwich alkylscandium species as a catalyst. The oxygen atom of the ether group plays an important role in controlling the selectivity, possibly by coordinating to the metal center. Even when a bulky tert-butyl(diphenyl)silyloxy group is used as the tether group, there is no loss of selectivity.
