126522-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126522-57-4 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, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126522-57:
(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*2)+(2*5)+(1*7)=114
114 % 10 = 4
So 126522-57-4 is a valid CAS Registry Number.
