15236-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15236-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,3 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 15236-02:
(7*1)+(6*5)+(5*2)+(4*3)+(3*6)+(2*0)+(1*2)=79
79 % 10 = 9
So 15236-02-9 is a valid CAS Registry Number.
