656237-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 656237-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,3 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 656237-85:
(8*6)+(7*5)+(6*6)+(5*2)+(4*3)+(3*7)+(2*8)+(1*5)=183
183 % 10 = 3
So 656237-85-3 is a valid CAS Registry Number.
