1259939-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1259939-85-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1259939-85:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*3)+(3*9)+(2*8)+(1*5)=219
219 % 10 = 9
So 1259939-85-9 is a valid CAS Registry Number.
