126522-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126522-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,2 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 126522-86:
(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*2)+(2*8)+(1*6)=119
119 % 10 = 9
So 126522-86-9 is a valid CAS Registry Number.
