87702-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87702-98-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87702-98:
(7*8)+(6*7)+(5*7)+(4*0)+(3*2)+(2*9)+(1*8)=165
165 % 10 = 5
So 87702-98-5 is a valid CAS Registry Number.
