87241-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87241-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87241-76:
(7*8)+(6*7)+(5*2)+(4*4)+(3*1)+(2*7)+(1*6)=147
147 % 10 = 7
So 87241-76-7 is a valid CAS Registry Number.
