59851-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59851-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,8,5 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 59851-15:
(7*5)+(6*9)+(5*8)+(4*5)+(3*1)+(2*1)+(1*5)=159
159 % 10 = 9
So 59851-15-9 is a valid CAS Registry Number.
