37440-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37440-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,4,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 37440-89:
(7*3)+(6*7)+(5*4)+(4*4)+(3*0)+(2*8)+(1*9)=124
124 % 10 = 4
So 37440-89-4 is a valid CAS Registry Number.
