415921-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 415921-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,5,9,2 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 415921-46:
(8*4)+(7*1)+(6*5)+(5*9)+(4*2)+(3*1)+(2*4)+(1*6)=139
139 % 10 = 9
So 415921-46-9 is a valid CAS Registry Number.
