132869-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132869-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,6 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132869-39:
(8*1)+(7*3)+(6*2)+(5*8)+(4*6)+(3*9)+(2*3)+(1*9)=147
147 % 10 = 7
So 132869-39-7 is a valid CAS Registry Number.
