Check Digit Verification of cas no
The CAS Registry Mumber 7790-58-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7790-58:
(6*7)+(5*7)+(4*9)+(3*0)+(2*5)+(1*8)=131
131 % 10 = 1
So 7790-58-1 is a valid CAS Registry Number.
