Check Digit Verification of cas no

The CAS Registry Mumber 1138342-57-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,3,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1138342-57:
(9*1)+(8*1)+(7*3)+(6*8)+(5*3)+(4*4)+(3*2)+(2*5)+(1*7)=140
140 % 10 = 0
So 1138342-57-0 is a valid CAS Registry Number.

Gold-catalyzed rearrangement of propargylic tert-butyl carbonates

Buzas, Andrea K.,Istrate, Florin M.,Gagosz, Fabien

, p. 1889 - 1901 (2009)

Diversely substituted 4-alkylidene-1,3-dioxolan-2-ones are efficiently synthesized by a gold(I)-catalyzed rearrangement of propargylic tert-butyl carbonates. The substrates are readily accessible and the transformation, which is performed under mild react
