849041-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849041-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,0,4 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 849041-81:
(8*8)+(7*4)+(6*9)+(5*0)+(4*4)+(3*1)+(2*8)+(1*1)=182
182 % 10 = 2
So 849041-81-2 is a valid CAS Registry Number.
