197007-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197007-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,0,0 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197007-68:
(8*1)+(7*9)+(6*7)+(5*0)+(4*0)+(3*7)+(2*6)+(1*8)=154
154 % 10 = 4
So 197007-68-4 is a valid CAS Registry Number.

, p. 1111 - 1122 (2007/10/03)
The primary hydroxyl groups (at C-6 and C-6′) in 2,3,4,3′4′-penta-O-benzyl-1′-O-methoxymethyl sucrose (2) can be reactively differentiated with tert-butyldiphenylsilyl chloride. Reaction of 2 with TBDPSC1 afforded only one monosilylated product protected
