16990-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16990-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16990-40:
(7*1)+(6*6)+(5*9)+(4*9)+(3*0)+(2*4)+(1*0)=132
132 % 10 = 2
So 16990-40-2 is a valid CAS Registry Number.
