1622161-89-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1622161-89-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,2,1,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1622161-89:
(9*1)+(8*6)+(7*2)+(6*2)+(5*1)+(4*6)+(3*1)+(2*8)+(1*9)=140
140 % 10 = 0
So 1622161-89-0 is a valid CAS Registry Number.
