212191-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212191-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 212191-99:
(8*2)+(7*1)+(6*2)+(5*1)+(4*9)+(3*1)+(2*9)+(1*9)=106
106 % 10 = 6
So 212191-99-6 is a valid CAS Registry Number.
