Check Digit Verification of cas no

The CAS Registry Mumber 125344-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,4 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125344-15:
(8*1)+(7*2)+(6*5)+(5*3)+(4*4)+(3*4)+(2*1)+(1*5)=102
102 % 10 = 2
So 125344-15-2 is a valid CAS Registry Number.

Tertiary amine-catalyzed (3+3) annulations of δ-acetoxy allenoates: Substrate scope, synthetic application and mechanistic insight

Ni, Chunjie,Zhou, Weiping,Tong, Xiaofeng

, p. 3347 - 3354 (2017)

Herein is reported the formal (3?+?3) annulations of δ-acetoxy allenoates with 1C,3O-bisnucleophiles by using 6’-deoxy-6’-perfluorobenzamido-quinine (5g) as the catalyst, providing rapid access to 4H-pyrans with excellent enantioselectivity. The reaction
