Check Digit Verification of cas no
The CAS Registry Mumber 56961-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56961-20:
(7*5)+(6*6)+(5*9)+(4*6)+(3*1)+(2*2)+(1*0)=147
147 % 10 = 7
So 56961-20-7 is a valid CAS Registry Number.
