771586-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 771586-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,1,5,8 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 771586-41:
(8*7)+(7*7)+(6*1)+(5*5)+(4*8)+(3*6)+(2*4)+(1*1)=195
195 % 10 = 5
So 771586-41-5 is a valid CAS Registry Number.
