817636-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 817636-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,7,6,3 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 817636-93:
(8*8)+(7*1)+(6*7)+(5*6)+(4*3)+(3*6)+(2*9)+(1*3)=194
194 % 10 = 4
So 817636-93-4 is a valid CAS Registry Number.
