632339-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 632339-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,2,3,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 632339-40:
(8*6)+(7*3)+(6*2)+(5*3)+(4*3)+(3*9)+(2*4)+(1*0)=143
143 % 10 = 3
So 632339-40-3 is a valid CAS Registry Number.
