Check Digit Verification of cas no
The CAS Registry Mumber 5788-58-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5788-58:
(6*5)+(5*7)+(4*8)+(3*8)+(2*5)+(1*8)=139
139 % 10 = 9
So 5788-58-9 is a valid CAS Registry Number.
