444885-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444885-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,8 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 444885-29:
(8*4)+(7*4)+(6*4)+(5*8)+(4*8)+(3*5)+(2*2)+(1*9)=184
184 % 10 = 4
So 444885-29-4 is a valid CAS Registry Number.
