97271-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97271-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,7 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97271-90:
(7*9)+(6*7)+(5*2)+(4*7)+(3*1)+(2*9)+(1*0)=164
164 % 10 = 4
So 97271-90-4 is a valid CAS Registry Number.
