Check Digit Verification of cas no
The CAS Registry Mumber 27970-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,7 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27970-79:
(7*2)+(6*7)+(5*9)+(4*7)+(3*0)+(2*7)+(1*9)=152
152 % 10 = 2
So 27970-79-2 is a valid CAS Registry Number.
