1322669-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1322669-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,2,6,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1322669-20:
(9*1)+(8*3)+(7*2)+(6*2)+(5*6)+(4*6)+(3*9)+(2*2)+(1*0)=144
144 % 10 = 4
So 1322669-20-4 is a valid CAS Registry Number.
