121910-33-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121910-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,1 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121910-33:
(8*1)+(7*2)+(6*1)+(5*9)+(4*1)+(3*0)+(2*3)+(1*3)=86
86 % 10 = 6
So 121910-33-6 is a valid CAS Registry Number.
