Check Digit Verification of cas no

The CAS Registry Mumber 328041-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,0,4 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 328041-62:
(8*3)+(7*2)+(6*8)+(5*0)+(4*4)+(3*1)+(2*6)+(1*2)=119
119 % 10 = 9
So 328041-62-9 is a valid CAS Registry Number.

Synthesis of substituted α-methylene-γ-butyrolactones from chloroformates via palladium catalysed cyclisation-anion capture

Grigg,Savic

, p. 2381 - 2382 (2000)

Cyclisation of chloroformates onto proximate alkyne functionality in the presence of a Pd(0) catalyst followed by anion capture affords α-methylene-γ-butyrolactone derivatives in moderate to good yields.
