89311-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89311-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,1 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89311-39:
(7*8)+(6*9)+(5*3)+(4*1)+(3*1)+(2*3)+(1*9)=147
147 % 10 = 7
So 89311-39-7 is a valid CAS Registry Number.
