Check Digit Verification of cas no

The CAS Registry Mumber 148628-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,6,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 148628-70:
(8*1)+(7*4)+(6*8)+(5*6)+(4*2)+(3*8)+(2*7)+(1*0)=160
160 % 10 = 0
So 148628-70-0 is a valid CAS Registry Number.

Stereoselective synthesis of functionalized butenolides by the photochemical rearrangement of [2,1]benzisoxazolequinone derivatives

Armesto, Diego,Rodriguez-Morgade, Salome,Ortiz, Maria J.,Vazquez, Purificacion,Torres, Tomas

, p. 3363 - 3368 (1997)

On direct irradiation 3-alkoxy[2,1]benzisoxazolequinones 1a, 1b, 1c, 1e and 3-N,N-dimethylamino[2.1]benzisoxazolequinone 1d undergo rearrangement to the corresponding γ-cyano alkylidenebutenolides 3 in high yield. The reaction is highly stereoselective fo
