Check Digit Verification of cas no

The CAS Registry Mumber 128917-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,1 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128917-42:
(8*1)+(7*2)+(6*8)+(5*9)+(4*1)+(3*7)+(2*4)+(1*2)=150
150 % 10 = 0
So 128917-42-0 is a valid CAS Registry Number.

, p. 1592 - 1598 (2002)

The photoreactions of α,β-unsaturated γ,δ-epoxy nitriles 1,2,13 and 16 with triethylamine give rise to novel 1:1 α-adducts (e.g.,5) efficiently. After treatment with silica gel, the adducts undergo retro-Michael reaction leading to the corresponding α-alk
