Check Digit Verification of cas no
The CAS Registry Mumber 774538-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,5,3 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 774538-96:
(8*7)+(7*7)+(6*4)+(5*5)+(4*3)+(3*8)+(2*9)+(1*6)=214
214 % 10 = 4
So 774538-96-4 is a valid CAS Registry Number.
