1456622-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1456622-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,6,6,2 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1456622-56:
(9*1)+(8*4)+(7*5)+(6*6)+(5*6)+(4*2)+(3*2)+(2*5)+(1*6)=172
172 % 10 = 2
So 1456622-56-2 is a valid CAS Registry Number.
