Check Digit Verification of cas no
The CAS Registry Mumber 78850-37-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,5 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78850-37:
(7*7)+(6*8)+(5*8)+(4*5)+(3*0)+(2*3)+(1*7)=170
170 % 10 = 0
So 78850-37-0 is a valid CAS Registry Number.
