671792-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 671792-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,1,7,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 671792-39:
(8*6)+(7*7)+(6*1)+(5*7)+(4*9)+(3*2)+(2*3)+(1*9)=195
195 % 10 = 5
So 671792-39-5 is a valid CAS Registry Number.
