56734-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56734-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,7,3 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56734-90:
(7*5)+(6*6)+(5*7)+(4*3)+(3*4)+(2*9)+(1*0)=148
148 % 10 = 8
So 56734-90-8 is a valid CAS Registry Number.
