650636-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 650636-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,0,6,3 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 650636-50:
(8*6)+(7*5)+(6*0)+(5*6)+(4*3)+(3*6)+(2*5)+(1*0)=153
153 % 10 = 3
So 650636-50-3 is a valid CAS Registry Number.
