64341-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64341-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64341-75:
(7*6)+(6*4)+(5*3)+(4*4)+(3*1)+(2*7)+(1*5)=119
119 % 10 = 9
So 64341-75-9 is a valid CAS Registry Number.
