97911-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97911-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,1 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97911-52:
(7*9)+(6*7)+(5*9)+(4*1)+(3*1)+(2*5)+(1*2)=169
169 % 10 = 9
So 97911-52-9 is a valid CAS Registry Number.
