Check Digit Verification of cas no

The CAS Registry Mumber 134936-26-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134936-26:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*6)+(2*2)+(1*6)=138
138 % 10 = 8
So 134936-26-8 is a valid CAS Registry Number.

Synthesis of serine analogues to be used as modified phospho acceptor sites in substrates of protein kinase C

Broxterman, H. J. G.,Liskamp, R. M. J.

, p. 46 - 52 (2007/10/02)

Serine and threonine analogues (compounds 2-6) are readily accessible by reaction of the anion of N,N-dibenzylglycine ethyl ester (1) with an appropriate carbonyl compound.These analogues will be incorporated into Protein Kinase C (PKC) substrates.The serine aldehyde derivative 7 was used for the preparation of the corresponding diethyl acetal 9.This compound was the starting material in the synthesis of the suicide precursor 8, featuring a reductive amination leading to 12 and a Lewis-acid-catalysed cyclization giving 8.
