122535-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122535-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,3 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122535-83:
(8*1)+(7*2)+(6*2)+(5*5)+(4*3)+(3*5)+(2*8)+(1*3)=105
105 % 10 = 5
So 122535-83-5 is a valid CAS Registry Number.
