Check Digit Verification of cas no

The CAS Registry Mumber 149203-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 149203-46:
(8*1)+(7*4)+(6*9)+(5*2)+(4*0)+(3*3)+(2*4)+(1*6)=123
123 % 10 = 3
So 149203-46-3 is a valid CAS Registry Number.

A New Approach to Phosphoserine and Phosphothreonine Synthons Suitable for the Stepwise Synthesis of Phosphopeptides.

Mora, N.,Lacombe, J. M.,Pavia, A. A.

, p. 2461 - 2464 (1993)

Several phosphoserine and phosphothreonine synthons suitable for the stepwise synthesis of phosphopeptides have been prepared.Treatment of methylthiomethyl (MTM) esters of either benzyloxycarbonyl (Z), tert-butyloxycarbonyl (Boc) and allyloxycarbonyl (Alloc) serine and/or threonine with phosphochloridate in pyridine, followed by MgBr2 cleavage of MTM in diethylether, afforded the title compounds in excellent yields.
