Check Digit Verification of cas no

The CAS Registry Mumber 861994-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,9,9 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 861994-92:
(8*8)+(7*6)+(6*1)+(5*9)+(4*9)+(3*4)+(2*9)+(1*2)=225
225 % 10 = 5
So 861994-92-5 is a valid CAS Registry Number.

New pyrano[3,4-b]indoles from 2-hydroxymethylindole and L-dehydroascorbic acid

Lavrenov, Sergey N.,Turchin, Konstantin F.,Korolev, Alexander M.,Anisimova, Olga S.,Preobrazhenskaya, Maria N.

, p. 6610 - 6613 (2005)

2-Hydroxymethylindole reacts with L-dehydroascorbic acid under mild conditions to give (3R,3aR,10cS)-3-[(1S)-1,2-dihydroxyethyl]-3a,10c-dihydroxy- 3a,5,6,10c-tetrahydrofuro[3′,4′:5,6]pyrano[3,4-b]indol-1(3H)-one. Its tosyl derivative undergoes cyclization to form a pentacyclic ketal derivative.
