Check Digit Verification of cas no

The CAS Registry Mumber 1443052-58-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,0,5 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1443052-58:
(9*1)+(8*4)+(7*4)+(6*3)+(5*0)+(4*5)+(3*2)+(2*5)+(1*8)=131
131 % 10 = 1
So 1443052-58-1 is a valid CAS Registry Number.

, p. 9709 - 9713 (2016)

Catalytic addition of chiral phosphine, that is, (R)- or (S)-SITCP, to an α-substituted allene ester generated a zwitterionic dipole. Under optimized reaction conditions, this dipole could engage isatine-derived N-Boc-ketimines in a novel mode of [3+2] an
