64039-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64039-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,0,3 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64039-88:
(7*6)+(6*4)+(5*0)+(4*3)+(3*9)+(2*8)+(1*8)=129
129 % 10 = 9
So 64039-88-9 is a valid CAS Registry Number.
