1147-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1147-97-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1147-97:
(6*1)+(5*1)+(4*4)+(3*7)+(2*9)+(1*7)=73
73 % 10 = 3
So 1147-97-3 is a valid CAS Registry Number.
