1620697-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620697-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,6,9 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620697-05:
(9*1)+(8*6)+(7*2)+(6*0)+(5*6)+(4*9)+(3*7)+(2*0)+(1*5)=163
163 % 10 = 3
So 1620697-05-3 is a valid CAS Registry Number.
