642443-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 642443-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,4,4 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 642443-50:
(8*6)+(7*4)+(6*2)+(5*4)+(4*4)+(3*3)+(2*5)+(1*0)=143
143 % 10 = 3
So 642443-50-3 is a valid CAS Registry Number.
