91397-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91397-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,9 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91397-37:
(7*9)+(6*1)+(5*3)+(4*9)+(3*7)+(2*3)+(1*7)=154
154 % 10 = 4
So 91397-37-4 is a valid CAS Registry Number.
