156564-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156564-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,6 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156564-04:
(8*1)+(7*5)+(6*6)+(5*5)+(4*6)+(3*4)+(2*0)+(1*4)=144
144 % 10 = 4
So 156564-04-4 is a valid CAS Registry Number.
