Check Digit Verification of cas no
The CAS Registry Mumber 7778-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7778-18:
(6*7)+(5*7)+(4*7)+(3*8)+(2*1)+(1*8)=139
139 % 10 = 9
So 7778-18-9 is a valid CAS Registry Number.
