Check Digit Verification of cas no
The CAS Registry Mumber 5920-20-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5920-20:
(6*5)+(5*9)+(4*2)+(3*0)+(2*2)+(1*0)=87
87 % 10 = 7
So 5920-20-7 is a valid CAS Registry Number.
