87617-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87617-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,1 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87617-38:
(7*8)+(6*7)+(5*6)+(4*1)+(3*7)+(2*3)+(1*8)=167
167 % 10 = 7
So 87617-38-7 is a valid CAS Registry Number.
