1693-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1693-90-9 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 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1693-90:
(6*1)+(5*6)+(4*9)+(3*3)+(2*9)+(1*0)=99
99 % 10 = 9
So 1693-90-9 is a valid CAS Registry Number.
