650605-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 650605-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,0,6,0 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 650605-52:
(8*6)+(7*5)+(6*0)+(5*6)+(4*0)+(3*5)+(2*5)+(1*2)=140
140 % 10 = 0
So 650605-52-0 is a valid CAS Registry Number.
