159255-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159255-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,2,5 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159255-57:
(8*1)+(7*5)+(6*9)+(5*2)+(4*5)+(3*5)+(2*5)+(1*7)=159
159 % 10 = 9
So 159255-57-9 is a valid CAS Registry Number.
