Check Digit Verification of cas no

The CAS Registry Mumber 109751-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,5 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109751-81:
(8*1)+(7*0)+(6*9)+(5*7)+(4*5)+(3*1)+(2*8)+(1*1)=137
137 % 10 = 7
So 109751-81-7 is a valid CAS Registry Number.

Bis(trimethylsiloxy)-1,1 butadiene-1,3 et trimethylsilyl-4 butene-2 oate de trimethylsilyle: preparations et reactions avec benzaldehyde

Bellassoued, M.,Ennigrou, R.,Gaudemar, M.

, p. 149 - 158 (1988)

The preparation of 4-trimethylsilyl-2-butenoate trimethylsilyl ester and 1,1-bis(trimethylsiloxy)-1,3-butadiene are described.The latter silyl derivative reacts with benzaldehyde in the presence of ZnBr2 in THF to give exclusively γ-substituted product (E configuration) in high yield.The fluoride ion catalyzed reaction affords predominantly α-alkylated compounds.
