Check Digit Verification of cas no
The CAS Registry Mumber 756526-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,5,2 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 756526-06:
(8*7)+(7*5)+(6*6)+(5*5)+(4*2)+(3*6)+(2*0)+(1*6)=184
184 % 10 = 4
So 756526-06-4 is a valid CAS Registry Number.
