87201-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87201-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,0 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87201-79:
(7*8)+(6*7)+(5*2)+(4*0)+(3*1)+(2*7)+(1*9)=134
134 % 10 = 4
So 87201-79-4 is a valid CAS Registry Number.
