Check Digit Verification of cas no
The CAS Registry Mumber 82942-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82942-26:
(7*8)+(6*2)+(5*9)+(4*4)+(3*2)+(2*2)+(1*6)=145
145 % 10 = 5
So 82942-26-5 is a valid CAS Registry Number.
