Check Digit Verification of cas no
The CAS Registry Mumber 125974-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,7 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125974-06:
(8*1)+(7*2)+(6*5)+(5*9)+(4*7)+(3*4)+(2*0)+(1*6)=143
143 % 10 = 3
So 125974-06-3 is a valid CAS Registry Number.

A mild, efficient and general method for the synthesis of trialkylsilyl (Z)-4-oxo-2-alkenoates and γ-hydroxybutenolides
Boukouvalas, John,Lachance, Nicolas
, p. 31 - 32 (1998)
2-Trialkylsilyloxyfurans react rapidly with dimethyldioxirane at -78°C to provide trialkylsilyl (Z)-4-oxo-2-alkenoates whose hydrolysis delivers γ-hydroxybutenolides with high efficiency; a short synthesis of a naturally occurring monoterpene γ-hydroxybutenolide (4) is reported.
