7097-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7097-63-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7097-63:
(6*7)+(5*0)+(4*9)+(3*7)+(2*6)+(1*3)=114
114 % 10 = 4
So 7097-63-4 is a valid CAS Registry Number.
