159755-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159755-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,5 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159755-13:
(8*1)+(7*5)+(6*9)+(5*7)+(4*5)+(3*5)+(2*1)+(1*3)=172
172 % 10 = 2
So 159755-13-2 is a valid CAS Registry Number.
