Check Digit Verification of cas no
The CAS Registry Mumber 100199-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,9 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100199-21:
(8*1)+(7*0)+(6*0)+(5*1)+(4*9)+(3*9)+(2*2)+(1*1)=81
81 % 10 = 1
So 100199-21-1 is a valid CAS Registry Number.

SYNTHESIS OF 2-AZOLYLCYCLOALKANOLS
Murabayashi, Akira,Makisumi, Yasuo
, p. 537 - 548 (2007/10/02)
New 2-azolylcycloalkanol derivatives (13-38) were synthesized stereoselectively by Grignard reaction of 2-azolylcyclohexanones (7,8), and particularly 2-azolylcycloheptanones (9,10) afforded one of the diastereomers of 2-azolylcycloalkanols stereospecific
