444987-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444987-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,9,8 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 444987-76:
(8*4)+(7*4)+(6*4)+(5*9)+(4*8)+(3*7)+(2*7)+(1*6)=202
202 % 10 = 2
So 444987-76-2 is a valid CAS Registry Number.
