216169-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216169-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,1,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216169-70:
(8*2)+(7*1)+(6*6)+(5*1)+(4*6)+(3*9)+(2*7)+(1*0)=129
129 % 10 = 9
So 216169-70-9 is a valid CAS Registry Number.
