Check Digit Verification of cas no

The CAS Registry Mumber 131700-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,0 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131700-95:
(8*1)+(7*3)+(6*1)+(5*7)+(4*0)+(3*0)+(2*9)+(1*5)=93
93 % 10 = 3
So 131700-95-3 is a valid CAS Registry Number.

CHIRAL TOLUENE-2,α-SULTAM AUXILIARIES: ASYMMETRIC ALKYLATIONS, ACYLATIONS AND ALDOLIZATIONS OF N-ACYL DERIVATIVES

Oppolzer, Wolfgang,Rodriguez, Ines,Starkemann, Christian,Walther, Eric

, p. 5019 - 5022 (1990)

Successive treatment of (R)-N-acylsultams 4 with NHDMS/alkyl halides or NHDMS/acyl chlorides provides alkylated or acylated products 6 or 7.Diastereoselective reductions of 7 with Zn(BH4)2 or NaHB(sBu)3 gives "syn"- or "anti"-aldols 8 or 9.Reaction of 4 with BEt3/TfOH/EtN(iPr)2 followed by addition of aromatic or aliphatic aldehydes affords diastereomerically pure "syn"-aldols 10.Non-destructive removal of auxiliary 3 from 6, 8, 9 and 10 yields enantiomerically pure products 12 to 16.
