664301-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 664301-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,0 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 664301-89:
(8*6)+(7*6)+(6*4)+(5*3)+(4*0)+(3*1)+(2*8)+(1*9)=157
157 % 10 = 7
So 664301-89-7 is a valid CAS Registry Number.
