843615-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 843615-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,3,6,1 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 843615-50:
(8*8)+(7*4)+(6*3)+(5*6)+(4*1)+(3*5)+(2*5)+(1*0)=169
169 % 10 = 9
So 843615-50-9 is a valid CAS Registry Number.
