663155-10-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 663155-10-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,3,1,5 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 663155-10:
(8*6)+(7*6)+(6*3)+(5*1)+(4*5)+(3*5)+(2*1)+(1*0)=150
150 % 10 = 0
So 663155-10-0 is a valid CAS Registry Number.
