404887-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 404887-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,8,8 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 404887-21:
(8*4)+(7*0)+(6*4)+(5*8)+(4*8)+(3*7)+(2*2)+(1*1)=154
154 % 10 = 4
So 404887-21-4 is a valid CAS Registry Number.
