97308-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97308-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,0 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97308-11:
(7*9)+(6*7)+(5*3)+(4*0)+(3*8)+(2*1)+(1*1)=147
147 % 10 = 7
So 97308-11-7 is a valid CAS Registry Number.
