132216-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132216-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,1 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132216-06:
(8*1)+(7*3)+(6*2)+(5*2)+(4*1)+(3*6)+(2*0)+(1*6)=79
79 % 10 = 9
So 132216-06-9 is a valid CAS Registry Number.
