4356-17-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4356-17-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4356-17:
(6*4)+(5*3)+(4*5)+(3*6)+(2*1)+(1*7)=86
86 % 10 = 6
So 4356-17-6 is a valid CAS Registry Number.
