62833-26-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62833-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,3 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 62833-26:
(7*6)+(6*2)+(5*8)+(4*3)+(3*3)+(2*2)+(1*6)=125
125 % 10 = 5
So 62833-26-5 is a valid CAS Registry Number.
