1287289-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1287289-15-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,2,8 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1287289-15:
(9*1)+(8*2)+(7*8)+(6*7)+(5*2)+(4*8)+(3*9)+(2*1)+(1*5)=199
199 % 10 = 9
So 1287289-15-9 is a valid CAS Registry Number.
