136934-29-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136934-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,3 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136934-29:
(8*1)+(7*3)+(6*6)+(5*9)+(4*3)+(3*4)+(2*2)+(1*9)=147
147 % 10 = 7
So 136934-29-7 is a valid CAS Registry Number.
