163719-80-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163719-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,1 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163719-80:
(8*1)+(7*6)+(6*3)+(5*7)+(4*1)+(3*9)+(2*8)+(1*0)=150
150 % 10 = 0
So 163719-80-0 is a valid CAS Registry Number.
