70875-30-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70875-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,7 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70875-30:
(7*7)+(6*0)+(5*8)+(4*7)+(3*5)+(2*3)+(1*0)=138
138 % 10 = 8
So 70875-30-8 is a valid CAS Registry Number.
