Check Digit Verification of cas no

The CAS Registry Mumber 1428188-87-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,8 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1428188-87:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*8)+(3*8)+(2*8)+(1*7)=187
187 % 10 = 7
So 1428188-87-7 is a valid CAS Registry Number.

Guidelines for β-lactam synthesis: Glycal protecting groups dictate stereoelectronics and [2+2] cycloaddition kinetics

Grinstaff, Mark W.,Balijepalli, Anant S.,McNeely, James H.,Hamoud, Aladin

, p. 12044 - 12057 (2020)

The alkene-isocyanate cycloaddition method affords β- lactams from glycals with high regio- and stereoselectivity, but the factors that determine substrate reactivity are poorly understood. Thus, we synthesized a library of 17 electron-rich alkenes (glyca
