1644077-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1644077-56-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,0,7 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1644077-56:
(9*1)+(8*6)+(7*4)+(6*4)+(5*0)+(4*7)+(3*7)+(2*5)+(1*6)=174
174 % 10 = 4
So 1644077-56-4 is a valid CAS Registry Number.
