Check Digit Verification of cas no
The CAS Registry Mumber 70381-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70381-75:
(7*7)+(6*0)+(5*3)+(4*8)+(3*1)+(2*7)+(1*5)=118
118 % 10 = 8
So 70381-75-8 is a valid CAS Registry Number.
