Check Digit Verification of cas no
The CAS Registry Mumber 75619-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,1 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75619-23:
(7*7)+(6*5)+(5*6)+(4*1)+(3*9)+(2*2)+(1*3)=147
147 % 10 = 7
So 75619-23-7 is a valid CAS Registry Number.
