121150-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121150-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121150-33:
(8*1)+(7*2)+(6*1)+(5*1)+(4*5)+(3*0)+(2*3)+(1*3)=62
62 % 10 = 2
So 121150-33-2 is a valid CAS Registry Number.
