70663-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70663-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,6 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70663-22:
(7*7)+(6*0)+(5*6)+(4*6)+(3*3)+(2*2)+(1*2)=118
118 % 10 = 8
So 70663-22-8 is a valid CAS Registry Number.
