562043-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 562043-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,2,0,4 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 562043-57:
(8*5)+(7*6)+(6*2)+(5*0)+(4*4)+(3*3)+(2*5)+(1*7)=136
136 % 10 = 6
So 562043-57-6 is a valid CAS Registry Number.
