6974-60-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6974-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,7 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6974-60:
(6*6)+(5*9)+(4*7)+(3*4)+(2*6)+(1*0)=133
133 % 10 = 3
So 6974-60-3 is a valid CAS Registry Number.

Literature N-alkylsaccharins (saccharin-R2) have been shown in some cases to be O-alkylated regioisomers by crystallography (3 structures). The genuine former species react with (S)-H2NCHR1CH 2OH at 101°C in dio
