162663-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162663-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,6 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 162663-65:
(8*1)+(7*6)+(6*2)+(5*6)+(4*6)+(3*3)+(2*6)+(1*5)=142
142 % 10 = 2
So 162663-65-2 is a valid CAS Registry Number.
