1690-30-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1690-30-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1690-30:
(6*1)+(5*6)+(4*9)+(3*0)+(2*3)+(1*0)=78
78 % 10 = 8
So 1690-30-8 is a valid CAS Registry Number.
