88320-37-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88320-37-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,3,2 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88320-37:
(7*8)+(6*8)+(5*3)+(4*2)+(3*0)+(2*3)+(1*7)=140
140 % 10 = 0
So 88320-37-0 is a valid CAS Registry Number.
