Check Digit Verification of cas no

The CAS Registry Mumber 216172-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,1,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 216172-25:
(8*2)+(7*1)+(6*6)+(5*1)+(4*7)+(3*2)+(2*2)+(1*5)=107
107 % 10 = 7
So 216172-25-7 is a valid CAS Registry Number.

Palladium-catalysed cyclisation of enantiopure allenic lactams prepared from a pyroglutamic acid derived organozinc reagent

Karstens, Willem F. J.,Stol, Marianne,Rutjes, Floris P. J. T.,Hiemstra, Henk

, p. 1126 - 1128 (1998)

A route for the synthesis of enantiopure allene-substituted lactams has been developed. The key-step involves the copper(I) mediated SN2' substitution of propargylic tosylates by a (S)-pyroglutamic acid derived organozinc reagent. Pd-catalysed
