389104-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 389104-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,1,0 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 389104-64:
(8*3)+(7*8)+(6*9)+(5*1)+(4*0)+(3*4)+(2*6)+(1*4)=167
167 % 10 = 7
So 389104-64-7 is a valid CAS Registry Number.
