132672-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132672-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,7 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132672-33:
(8*1)+(7*3)+(6*2)+(5*6)+(4*7)+(3*2)+(2*3)+(1*3)=114
114 % 10 = 4
So 132672-33-4 is a valid CAS Registry Number.
