87605-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87605-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,0 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87605-41:
(7*8)+(6*7)+(5*6)+(4*0)+(3*5)+(2*4)+(1*1)=152
152 % 10 = 2
So 87605-41-2 is a valid CAS Registry Number.
