89937-00-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89937-00-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,3 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89937-00:
(7*8)+(6*9)+(5*9)+(4*3)+(3*7)+(2*0)+(1*0)=188
188 % 10 = 8
So 89937-00-8 is a valid CAS Registry Number.
