69319-30-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69319-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69319-30:
(7*6)+(6*9)+(5*3)+(4*1)+(3*9)+(2*3)+(1*0)=148
148 % 10 = 8
So 69319-30-8 is a valid CAS Registry Number.
