97855-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97855-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,8,5 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97855-73:
(7*9)+(6*7)+(5*8)+(4*5)+(3*5)+(2*7)+(1*3)=197
197 % 10 = 7
So 97855-73-7 is a valid CAS Registry Number.
