884660-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 884660-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,4,6,6 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 884660-31:
(8*8)+(7*8)+(6*4)+(5*6)+(4*6)+(3*0)+(2*3)+(1*1)=205
205 % 10 = 5
So 884660-31-5 is a valid CAS Registry Number.
