104387-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104387-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,8 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104387-46:
(8*1)+(7*0)+(6*4)+(5*3)+(4*8)+(3*7)+(2*4)+(1*6)=114
114 % 10 = 4
So 104387-46-4 is a valid CAS Registry Number.
