Check Digit Verification of cas no
The CAS Registry Mumber 16642-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,4 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16642-52:
(7*1)+(6*6)+(5*6)+(4*4)+(3*2)+(2*5)+(1*2)=107
107 % 10 = 7
So 16642-52-7 is a valid CAS Registry Number.
