59156-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59156-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,5 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59156-99:
(7*5)+(6*9)+(5*1)+(4*5)+(3*6)+(2*9)+(1*9)=159
159 % 10 = 9
So 59156-99-9 is a valid CAS Registry Number.
