Check Digit Verification of cas no

The CAS Registry Mumber 1334481-84-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,4,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1334481-84:
(9*1)+(8*3)+(7*3)+(6*4)+(5*4)+(4*8)+(3*1)+(2*8)+(1*4)=153
153 % 10 = 3
So 1334481-84-3 is a valid CAS Registry Number.

A large-scale preparation of (3S,4S)-3-(tert-butoxycarbonyl)amino-4-methylpyrrolidine and its analogs from L-aspartic acid

(3S,4S)-3-(tert-Butoxycarbonyl)amino-4-methylpyrrolidine (12a) was synthesized from L-aspartic acid (4) on a large scale. Methylation of dimethyl (2S)-N-benzyl-N-(9-phenylfluoren-9-yl)aspartate (5), easily derived from 4, with methyl iodide gave (3R)-3-methylaspartate (6a) in 91% yield with high diastereoselectivity. Reduction of 6a with lithium aluminum hydride, followed by hydrogenolysis, protection with di-tert-butyl dicarbonate, and mesylation gave 10a in 89% overall yield. Subsequently, reaction of 10a with benzylamine under a nitrogen atmosphere at room temperature, followed by hydrogenolysis, gave the target compound (12a) in 65% overall yield. In a similar manner to that described for the preparation of 12a from 5, compound 5 was converted into 4-ethyl and 4-propyl derivatives (12b,c) in 34% and 38% overall yields.
