Check Digit Verification of cas no

The CAS Registry Mumber 128910-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,1 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128910-58:
(8*1)+(7*2)+(6*8)+(5*9)+(4*1)+(3*0)+(2*5)+(1*8)=137
137 % 10 = 7
So 128910-58-7 is a valid CAS Registry Number.

AN EFFICIENT SYNTHETIC ROUTE TO γ,δ-UNSATURATED SEVEN-MEMBERED LACTONES

Kido, Fusao,Kazi, Abul B.,Yamaji, Kazuo,Kato, Michiharu,Yoshikoshi, Akira

, p. 607 - 618 (2007/10/02)

Treatment of the diazomalonates (9a-d) of 2-phenylthio-3-butenol derivatives with catalytic rhodium acetate resulted in the sigmatropic rearrangement of six-membered allylsulfonium ylides to provide γ,δ-unsaturated seven-membered lactones (10a-d) in

New Entry to γ,δ-Unsaturated Seven-membered Lactones

Kido, Fusao,Kazi, Abul B.,Yoshikoshi, Akira

, p. 613 - 616 (2007/10/02)

The sigmatropic rearrangement of cyclic allyl-sulfonium ylides, generated from the diazo malonates of 2-phenylthio-3-butenol derivatives with catalytic rhodium acetate, afforded γ,δ-unsaturated seven-membered lactones in moderate to good yields.
