132281-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132281-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,8 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132281-69:
(8*1)+(7*3)+(6*2)+(5*2)+(4*8)+(3*1)+(2*6)+(1*9)=107
107 % 10 = 7
So 132281-69-7 is a valid CAS Registry Number.
