844699-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 844699-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,6,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 844699-34:
(8*8)+(7*4)+(6*4)+(5*6)+(4*9)+(3*9)+(2*3)+(1*4)=219
219 % 10 = 9
So 844699-34-9 is a valid CAS Registry Number.
